The diff and merge viewers had no overview lane, so changes outside the viewport were invisible. The scrollbar now marks every change, coloured by type (modified, inserted, deleted, conflict), in the side-by-side view (both panes), the aligned view (one stripe over the shared scroller), the unified view and the three-way merge editor; clicking a mark jumps to the change. Marks span the lane's width from the first to the last changed line with a 2px minimum. The colours are new --diff-*-stripe theme tokens (Darcula, Light and High-contrast values), mapped from ERROR_STRIPE_COLOR on .icls import and set in the Harbor Night theme template.

Harbor Night
An OpenIDEA theme plugin, Harbor Night: a dark theme with slate surfaces, a
teal accent and a warm syntax palette. It is also where new themes start:
openidea-plugin new --template theme copies its theme files, or copy this
folder. Full documentation, the token reference and porting guides are in
docs/plugins/themes.md.
harbor-night/
├─ plugin.toml # manifest: id, name, version, the theme files
└─ themes/
├─ harbor-night.theme.json # UI colours, every themeable token, grouped like tokens.css
└─ harbor-night.scheme.json # editor colour scheme: syntax, editor, ANSI colours
A theme plugin is data only: no code, no WebAssembly, no build step.
Make your own
- Run
openidea-plugin new --template theme, or copy the folder, for example to~/openidea-themes/my-theme. - In
plugin.toml, changeid(lowercase,a-z 0-9 - _ .),name,description,authorsand the two paths. - Rename the theme files. In the theme file, set
id,nameandkind("dark"or"light", the built-in base for anything you leave out). - Edit the colours. Each key is a CSS variable from
src/styles/tokens.css, and the reference in the docs gives the Islands Dark and Light values. Comments (//,/* */) are allowed. Delete a line to keep the built-in value.
Porting an IntelliJ theme? pnpm theme:import-intellij <file.theme.json> [file.icls] --out <dir>
in the OpenIDEA repository generates a package in this layout.
Package and install
The folder is the package. To share it, publish the folder as a Git repository or a zip that users extract.

Iterate
Put (or symlink) the folder in <project>/.openidea/plugins/ of an open
project. It loads as a dev plugin, and Reload in Settings › Plugins (or
the Reload Plugins action) re-reads your edits without reinstalling. Invalid
JSON or values are reported in Settings › Plugins with the file and line.
