The custom font block laid its three fields out as inline flex options that wrapped freely, so the UI font picker, the fallback font picker and the Size input started at different x positions depending on what preceded them on their wrapped line. The block is now a two-column grid: the Use custom font checkbox, the Fallback font label and the Size label share one label column, and all three controls start at the same x, matching the Editor > Font page and IntelliJ's Settings > Appearance layout. The change is scoped to the Appearance page's own CSS module; no shared form styles are touched. Signed-off-by: Inf1mum <[email protected]>

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
Plugins
Plugins add actions, completion, quick fixes, tool windows, custom editors, themes, file icons and languages. They run as sandboxed WebAssembly components; themes, icon themes and languages need no code at all.
Install them from Settings › Plugins, or start your own with
openidea-plugin new — see Writing OpenIDEA plugins and
the official plugins. The plugin API is still a preview.
