The find bar belonged to the pane and every bar shared one query, and its effect re-ran the search and moved the caret whenever the active tab changed, so switching files dragged the previous file's search into the next one and lost its caret. Each tab now has its own find bar with its own query and options, as with IDEA's per-editor search session. The last search only pre-fills a newly opened bar (or the selection does) and drives Find Next without a bar; showing a bar again only highlights, and the caret moves only when the query or an option changes in that bar. Bars of closed tabs are dropped. Co-authored-by: jaw52 <53564781+jaw52@users.noreply.github.com>

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.
