Reformat Code only asked the language server for formatting, so files whose server has no formatting capability (Markdown with marksman, and others depending on the server) could not be formatted.
Languages can now declare an external formatter. Prettier is the first: a managed tool installed on demand, or the project's own node_modules/prettier, an explicit path, or PATH. It runs on the backend copy of the document with the file's path so Prettier resolves the project's config, overrides and ignore files, and its result is applied as one undoable edit. Language servers that format a file keep doing so unless Prettier is preferred in Settings › Languages › Prettier; formatting on save is opt-in. Parsers without range support format the whole file and say so.
Errors carry structured tool data, so a missing Prettier reuses the shared install prompt and Prettier diagnostics or timeouts show as non-sticky notifications.
Fixes#639
The editor's mousedown handler ignored every button except the left one, so a middle click fell through to the webview's autoscroll. A plain middle click now moves the caret to the clicked symbol and runs go-to-definition, suppressing autoscroll; a keymap shortcut bound to Button2 still takes precedence, and modifier + middle combinations stay unbound.
Fixes#663

In files no language server covers (Markdown, .properties, plain text), Shift+F6 only showed a transient "no running language server supports rename" hint at the caret, so the default rename shortcut looked broken.
Root cause: when prepare_rename reported no server and the syntax fallback declined, startRename fell through to the error hint. It now hands off to project.rename, which opens the file rename dialog for the active file; a running server that lacks rename keeps its hint.
Verified on macOS: Shift+F6 in .md and .properties editors renames the file, symbol rename in TypeScript is unchanged, and Shift+F6 in the project view still renames the selected file.

Opening a .class file showed binary content. Class files from library jars, project output directories, navigation, Go to Class and debugger frames now all go through one route to JDT class documents:
- Library classes open the attached source, or the FernFlower decompilation when there is none, read-only and marked as decompiled. java-debug's decompiled-source support is enabled, so breakpoints set in decompiled code map to the original lines and hit, and stepping into such classes lands on the right line.
- Output-directory classes (target/classes, build/classes) open their project source when it exists; otherwise the decompiled text is shown read-only with breakpoints disabled, because jdt.ls returns no line mapping for classes outside the Java model.
- The preferred content provider id is corrected to fernflowerContentProvider (attached sources still win), and the decompiled marker recognises the current FernFlower header.
Verified on macOS with a Maven project: library class from Libraries and Go to Class, breakpoint hit and step into decompiled code, output class with and without source. Not run on Windows, Linux or Gradle projects.
Fixes#394
Agent sessions can be opened in the Agents tool window beside the editor (Open in Tool Window / Open in Editor in the task menus, or by dragging between the editor and the tool window); opening in an editor tab stays the default.
Fixes in review:
- A docked conversation kept the previous task's subagent view after switching tasks: the session's local state is now keyed by task.
- Moving a conversation between the editor and the tool window lost its scroll position: position and follow-output are kept per conversation (task or subagent).
- In a short bottom tool window the message area shrank to a few pixels: wide windows place the task list beside the conversation, narrow ones cap the list height.
- Drag and drop and list selection now go through the agents.dockTask / undockTask / openTask actions.

applyCodeAction now resolves the picked action and executes it (lspResolveCodeAction → lspExecuteCodeAction) instead of calling lspApplyCodeAction, but refactorThis.test.ts and runKind.test.ts still mocked and asserted the old command, so main's frontend tests failed (4 tests). The mocks now follow the new commands; safeDelete.test.ts's negative assertion still holds.

Go's test generation and interface stubs were reachable only through context actions, because Generate filtered their titles, and implementing an interface on a plain struct wasn't available since the client didn't support gopls's interactive commands.
Generate and the editor's context menu now list `Add test for ...`, `Declare missing methods ...` and `Add methods to ... implement ...`, and a generated test file opens in the editor. For gopls only, the client advertises `interactiveResolve` and runs its `command/resolve` handshake: a prompt titled from the server asks for the interface, shows validation errors in place, and Cancel writes nothing. Requests are cancellable and other servers and existing commands are unchanged.
Fixes#620
* fix(editor): pause expensive decorations during fast scroll bursts
Add a scrollThrottle plugin that flags the editor with a .cm-scrolling
class while the wheel is moving. While the flag is up the sticky-scroll
header and indent guides are hidden via theme CSS, and their view
plugins skip per-viewport re-measures/rebuilds; a trailing scrollSettled
effect re-runs them once the wheel rests for 140ms. This keeps fast
mouse-wheel scrolling from painting rows of stale decorations over
freshly rendered code.
Fixesl0ng-ai/openidea#375
* fix(editor): keep decorations painted during scroll bursts
The scroll throttle hid the sticky header and indent guides entirely while
scrolling, which flickered on every burst - and the sticky header is exactly
what you want to see while scrolling. Drop the display/background hiding from
the theme and keep the previous paint instead: the plugins skip re-measuring
during a burst and catch up once on the trailing scrollSettled update.
* fix(editor): throttle the first scroll event and queued sticky measurements

Native folding matched comment node names case-sensitively and stripped delimiters character by character, so XML comments were skipped and the `<` in editor-fold tags was consumed. The frontend hardcoded its own comment prefixes. Both now strip the configured comment tokens from the language definitions, so region and editor-fold markers work in block comment languages (XML, HTML, Vue, SVG, CSS and others), and Navigate > Custom Folding lists them. Languages without a bundled grammar get a fallback for own-line markers. Rust and frontend tests share one fixture over 22 language configurations.
Fixes#583
Pasting files copied in the project view into a Markdown document now inserts `[](relative/path)`, one link per line, encoded the same way as Markdown images. Other editors and terminals keep inserting the raw path, copied images keep their  route, and remote windows keep raw paths because the clipboard holds client paths. A context-menu Paste that the native command rejects falls back to reading the clipboard.
Fixes#573
Copying files in the project view wrote only the file list to the OS clipboard, so pasting into an editor did nothing. The copy now also writes the newline-separated paths as text, which other applications can paste.
WKWebView hides that text when file URLs are present and delivers a paste event with only Files, so the IDE editor and terminal still received nothing. A shared helper now reads the OS file list when a paste has files but no text, and inserts the paths. It covers Cmd+V and context-menu Paste in the editor, the terminal and embedded terminals. Markdown image paste runs first and keeps its behaviour.
Verified on macOS. The Windows clipboard change was tested by the contributor at the clipboard level only.

Add Shift+left-click as a way to close editor tabs. The tab strip gets a closeOnShiftClick option, enabled for the editor area only, so tool window tabs such as Run and Terminal still select on Shift+click. Keyboard activation with Shift held still selects, non-closable tabs still select, and Shift+click does not start a tab drag.

Projects now open with a user-owned trust decision. The prompt offers Preview in Restricted Mode, Don't Open and Trust Project, with an optional trusted parent folder; preview is the default focus so Enter never grants trust.
Restricted projects keep browsing, editing, saving, search and highlighting. Project-controlled execution is denied by default in the backend: run, debug, build, tools, language servers, plugins and Git commands that could honour repository configuration. Trusting a project enables those paths without reopening it, and decisions can be revoked in Settings.
Terminals stay available when the user opens one, without project shell settings, environment or virtualenv activation. A shell prompt that runs git in the folder can still honour the repository's core.fsmonitor.
Fixes#462
Markdown layout controls occupied a permanent bordered popup over the document.
- Move them into the editor tab strip with layout icons. When tabs are hidden, including Distraction Free Mode, show one floating toolbar that appears on mouse activity and fades after inactivity.
- Use the same floating toolbar for the HTML browser controls.
- Keep keyboard access: hold the toolbar while focused, return focus on Escape, and respect reduced motion. Add theme tokens with their import, template and reference entries.
Open files only reloaded from file watcher events, so a change the watcher skipped stayed stale in its tab: excluded and git-ignored folders, files outside the project, and missed events.
- Re-check open documents against disk when the window gains focus, off the UI thread and debounced. Clean documents reload, dirty ones keep the existing warning, and unchanged ones cost one metadata call.
- Refresh the project tree and Git status on the same focus event.
- Add "Synchronize external changes when switching to the IDE window" under System Settings, on by default.
Fixes#563
C/C++ files in a CMake project ran as standalone compiler commands, so multi-source programs failed to link. Single-file debugging selected CodeLLDB although the language uses lldb-dap. File aliases such as /tmp and /private/tmp could apply one rename edit twice. CMake command names were highlighted as variable definitions.
- Add CMake Configure, Build and CTest configurations, and read the File API codemodel after configuring to discover executable targets and their sources. Context runs select the owning target and build it first. Configuring only runs before the first build, since a configured build directory regenerates by itself.
- Debug C/C++ files and CMake targets with lldb-dap, and map CMake's recorded source root to its canonical path so breakpoints resolve.
- Coalesce file aliases and duplicate edits before preview and application, deduplicate references, and avoid reopening an open document through an alias.
- Replace the CMake syntax mode with command, argument keyword, predefined variable, boolean, number, string, comment and expansion highlighting.
The in-file Find bar had no way to see all matches at once.
Its new More menu adds Open Results in Find Window (Alt+F7 while the bar has focus), which lists the current query's matches as an Occurrences tab in the Find tool window, using the open editor text and the case, word, regex and selection options. The menu also has the multiple-cursor occurrence actions and a Scroll to Results During Typing toggle.
Fixes#523
The Color Scheme page only offered built-in schemes, so a scheme from another IDE could not be used.
Import reads .icls files into named custom schemes in user settings, reports applied and skipped values, and rejects malformed files. Export writes the current scheme, replacing an existing file, and custom schemes can be deleted. Colours are validated before reaching a stylesheet, and project settings cannot define schemes. The Appearance selector and Quick Switch list custom schemes too.
Fixes#513
Project rows only showed generic folder and filename icons, so JVM modules, packages and declarations looked alike.
Rows now show Maven and Gradle project and module icons, packages, Spring configuration and Boot application classes, runnable classes, test classes, Java and Kotlin declaration types, and generated, compiled and javadoc output folders. Editor tabs, Goto File and Recent Files use the same resolver. Types come from a bounded syntax parse of visible files, served locally and over remote RPC.
Spring stereotypes keep their ordinary type icons, and .class files stay binary.
Fixes#347
Pasting or dropping an image into a Markdown editor saves it beside the document in `assets/` and inserts a URL-encoded relative link as one undo step, in local and remote projects. Existing names get numbered suffixes; the folder and clipboard name pattern are in Settings › Editor › General. Non-Markdown editors, text paste and other dropped files keep their behavior.
Fixes#308
Replaces the Pull Requests tool window with a full review workflow on top of gh's authentication.
- List with search, quick filters and paging; a tab per pull request and a New Pull Request tab.
- Details: commit picker, changes tree with viewed state, CI and reviewer status, merge, close and reopen.
- Timeline editor: comments, review threads, reactions and suggested changes.
- Review in the diff viewer and, for the checked-out branch, in the editor (review mode).
- New generic vcs extension points: registerDiffViewerProvider, lineInlays, reviewGutter, branch widget extensions; new vcs_merge_base and gh_api commands.
- CSP: img-src allows https://avatars.githubusercontent.com for avatars.
Fixed while testing against a real repository: remotes behind an SSH host alias, mergeability stuck on UNKNOWN, Apply Locally staying disabled after a checkout, relative links navigating the app's page, and review inlays wider than the pane.

Dragging an editor tab past the window edge, or choosing Open in New Window from its menu, now opens the file in its own window and closes the tab here. A text file is saved first and a custom document runs its Save / Do not Save / Cancel guard once; if saving or opening fails, the tab stays. The new window is forced even when the project is already open elsewhere, and a file outside the project opens as LightEdit.
Dragging out tool windows is not covered. Refs #454

Angular templates left parts of their syntax uncoloured or misparsed, and control-flow blocks could not be folded. Binding names such as (keydown.escape) and [style.width.%] now take one colour and parse; structural directive values are parsed as microsyntax rather than JavaScript statements; block keywords are keywords only where one can appear; ?. is styled like . in templates and in JS and TS files; @if, @for, @switch, @defer and related blocks fold from { to } with the closing brace left visible.

The Windows/Linux keymap only bound the Ctrl+Alt+B stroke to navigate.implementation, so the click gesture that #405 made remappable did nothing there. Adds Ctrl+Alt+Button1 alongside the existing macOS Meta+Alt+Button1 binding; other Alt-click gestures are unaffected because column mode and multi-caret need different modifiers.

Workspaces open several local project folders in one IDE session (File › New / Open / Manage Workspace…, or Attach when opening a project, which creates a workspace automatically for a plain project window). Member folders are the Project view roots and take part in indexing, Find in Files, Git, language servers, run configurations and builds; agent tasks choose which member they work in. Window › Merge All Project Windows groups project windows into one window with project tabs (switch, reorder, close, move to a new window), restored on reopen.

Rename and incoming calls open the project files that mention the name, like
Find Usages, but dropped the reason a search could miss usages and could not be
cancelled. A rename past the 300-file limit changed part of the usages without
saying so.
- Rename and call hierarchy return why the result may be incomplete and take a
request id for cancel_request.
- A rename that may have missed usages always opens the preview, with a warning.
- The Callers tree shows the note above the tree or on the expanded node.
- Candidates too large or not readable as text are reported as skipped.
- A newer rename or hierarchy query cancels the one it replaces.
The mouse shortcut recorder accepted only side buttons, so a modified left click such as Option+Command+click couldn't be assigned. Left clicks with Ctrl, Alt or Command now record and dispatch as mouse shortcuts (plain and Shift-only clicks, middle and right clicks keep their meaning; unbound combinations behave as before). In editors the caret moves to the clicked position before the action runs, so navigation targets the symbol under the pointer. The macOS keymap binds Option+Command+click to Go to Implementation(s).

PHP language constructs such as empty and isset had no completion documentation, hover or quick documentation because the language server reports them as plain keywords. They now get built-in documentation in completion, hover, quick documentation and Go to Declaration (which shows the docs instead of failing), without matching strings, comments, methods or other languages. A refused syntax-based rename now states why the language server couldn't rename first.

The merge view blamed both side panes against HEAD, so lines that only exist on the merged branch showed as Not Committed Yet. vcs_blame takes an optional revision (validated, passed to git blame --contents -); the merge view blames Yours on HEAD and Theirs on MERGE_HEAD (swapped during a rebase).

The file watcher dropped events for a directory that matched an exclude or .gitignore rule together with its contents, so a target/ or node_modules/ created by a build never appeared in the Project view. The directory's own create/remove now passes through (it shows as excluded/ignored) while its contents stay filtered. Scrollbar lane marks also recompute on viewport changes, since unmeasured line heights shift as more of the document is measured.

The CodeMirror stream modes for these languages consumed string templates as one string token. A shared wrapper now splits template delimiters ($name, ${...}, C# {...}) from literal text and tokenizes the embedded code with the language's own mode, keeping nested braces, strings, escapes and multiline state; shell parameter, command and arithmetic expansions get the same treatment. Delimiters use the existing special-brace scope. JS/TS, Python, PHP, Swift and Ruby already tokenized embedded code and are unchanged.

- Git › Show History is offered for folders, multi-selection and the project root, not just single files.
- The Push dialog lets you pick any configured remote; pushing to another remote keeps the upstream's branch name and shows outgoing commits against that remote's branch.
- The Changes toolbar gains New Changelist (changelists already supported new/edit/delete/set active/move).
- Compare with Current gains Show Diff, opening the whole-project diff between the branch and HEAD.

Generate Request in HTTP Client (and Generate Requests for Controller, and the gutter icon) left the scratch file empty on Windows with "Cannot open file …\ai.l0ng.openidea/scratches/generated-requests.http": the scratch path joined the native app data directory (backslashes) with a /-separated suffix, so the opened editor could not be found by its path. Scratch paths now normalise the app data directory to the UI's /-separated form through a shared ipcPath helper, used by scratches, the HTTP client and Spring request generation.

The plain run glyph renders at 12px and the other gutter icons (run-all, run status badges, inheritance markers, HTTP request markers) at 14px through a shared gutterIconMarkup, so they look the same size. Run, Docker, HTTP, Spring HTTP and inheritance markers use it, and marker boxes are 14px to match the gutter column instead of overflowing it at 16px.
Accepting an LSP completion after typing more characters than the request saw (`System.out.` requested, then `Print` typed while the cached list stayed open) inserted the item after the typed text: `System.out.Printprint()`. The cached edit range started exactly at the request caret and was mapped forward past the newly typed characters. The range start now stays at the request caret, so the typed prefix is replaced, whatever its casing. Enter (insert) and Tab (replace) keep their behaviour for the text after the caret; this applies to every language server.
Fixes#316
HTML files in Angular projects were highlighted as plain HTML. Languages can now declare framework UI modes with root markers (angular.json, node_modules/@angular/core); files under such a root get the framework's editor mode, re-detected when a marker appears or disappears, and the root-marker lookup is shared with language server roots. The Angular Template mode (vendored @codemirror/lang-angular, MIT) adds @if/@for/@switch/@defer/@let blocks, key and animation binding names, and colours {{ }} delimiters.
Lazily loaded editor modes are now loaded before a document's first editor opens, so a file never renders as plain text first (this also left Angular templates uncoloured).

Opens .ipynb files in a native notebook editor, in a project or LightEdit.
- crates/ide-notebook: lossless nbformat documents (unchanged notebooks save byte-for-byte, unknown fields kept, external changes detected) and owned local kernels over ZMQ via kernelspec — the selected Python environment only needs ipykernel, no Jupyter server.
- ide-host owns notebook documents per project incarnation and admits one execution batch at a time; outputs stream over IPC channels and kernel status is an IdeEvent.
- src/features/notebook: virtualized Python/Markdown cells, insert/delete/move/change type, Run Cell / Run All (Shift+Enter), interrupt, restart, interpreter selection from ide-sdk discovery, shared split views. Raw/unknown cells stay read-only.
- Custom editor kinds take part in dirty state, save/save all, undo/redo and Save/Don't Save/Cancel; closing editors from other features awaits that decision.
- Outputs: text, tracebacks, PNG/JPEG and sanitized SVG inline; HTML sanitized in a sandboxed iframe without allow-same-origin; JavaScript output is shown as inert source.
- Explicit launches (opening a notebook from the OS) win over session restoration.

The status-bar breadcrumbs, the code breadcrumbs and the closed Navigation Bar popup subscribed to the whole editor status, which is replaced on every keystroke and caret move, so ~30 crumb buttons re-rendered per key.

ide-lsp returned the same `unavailable` error whether no server was running or a running server didn't implement the request, so the UI said no language server was available, and Invoke Inline Completion said no language server provides inline completion, while jdtls was running fine (it doesn't implement textDocument/inlineCompletion). When servers are running but none supports the feature, the error now names them ("jdtls doesn't support inline completion"), and every explicit action shares one message helper: Invoke Inline Completion, go to declaration / implementation / type declaration, quick documentation, parameter info, rename, reformat, intention actions, highlight usages, call / type hierarchy, find usages, safe delete and workspace symbols. With no server running it still says no language server is available. Background requests while typing stay silent.

Column-based editing computed columns with countColumn / findColumn, which count every grapheme as one column, and up/down and Clone Caret moved by pixel x, so block selections and cloned carets drifted on lines with CJK, fullwidth punctuation, Hangul, kana or emoji.

It drives Alt+drag block selection, drag and Shift+arrows in Column Selection Mode, middle-drag block selection (new; not on Linux, where middle-click pastes the primary selection), the up/down goal column (kept across short lines; soft-wrapped and folded lines still move visually), Clone Caret Above/Below, the caret move after Comment Line, Tab padding to the next indent stop, and macro playback of arrow keys.
