* feat(editor): Drag tabs and files between split panes
HTML5 drag and drop never reaches the webview while native file drop is
enabled, so tab, project-file and changelist drags did nothing. They now
run on pointer events:
- Drag an editor tab onto another pane, or onto a pane's edge to split it.
- Drag files from the Project view into an editor pane (center opens them
there, an edge opens them in a new split).
- Drag files between changelists in the Commit view.
- "Drag-and-drop with Alt pressed only" applies to tabs and stripe buttons.
* fix(lsp): Deliver server settings and start servers on a supported JDK
- workspace/configuration answers a server's own section (basedpyright)
from its settings block; basedpyright runs in "standard" mode and keeps
auto search paths on, so `src/` layouts resolve from `tests/`.
- jdtls: formatting follows the editor indent, calls complete without
guessed arguments, and JDK internals stay out of completion.
- `max-java` in a language server config picks an installed JDK no newer
than that (kotlin-language-server fails on JDK 25).
- Server initialization may take up to 5 minutes (first Gradle import).
- `lsp_resend_diagnostics` re-emits stored diagnostics after a reload.
- Spelling only checks declared names (not called methods like
`substring`) and accepts plurals of known software terms.
* feat(editor): Quick fixes, completion and navigation while typing
Quick fixes
- Errors get a red quick-fix bulb; Apply Quick Fix (⌥⇧↵) fixes the most
severe problem at the caret, and the error hover offers the fix directly.
- Code generated by a code action is re-indented to the file's style.
- Python: Implement abstract methods (⌃I or the bulb) from the bases.
- Duplicate code actions are listed once.
Completion
- Overloads sharing a name, and a name importable from several modules,
are no longer merged into one entry.
- Auto-import entries show the module they import from.
- Call snippets without a stop (`new ArrayList<>()`) leave the caret inside
the parentheses with parameter info, or past them when nothing takes
arguments; parameter info also opens after server call snippets.
- The selected item is resolved ahead of acceptance, so its auto-import
is applied (rust-analyzer).
Navigation and diagnostics
- Language server requests wait for pending edits, so Go to Declaration
right after typing answers for the current text; an empty answer right
after an edit is retried while the server catches up.
- Diagnostics come back after a window reload; error underlines stay
visible under typo / unused highlighting.
- Implementation gutter markers no longer refresh in a loop while the
server reports progress.
- A missing alternative server no longer shows as a server error.
* chore(lint): Skip agent worktrees under .claude
* fix(editor): Skip cancelled LSP requests and limit generated-code reformat
- Requests cancelled while waiting for pending edits are not sent.
- Code generated by an action is reformatted per changed hunk, so an added
import doesn't reformat the code between it and the generated lines.
- A long busy spell caused by a settle refresh re-runs it only once.
- Files dropped on a file row of another changelist move to that changelist.
- Python Implement methods: a nested class without bases ends the lookup,
class bodies continue through unindented string lines, and
`@abstractproperty` stubs become `@property`.
- Resend diagnostics goes through the host ops, and custom servers get
`max_java`.
* fix(editor): Rank the exact type first in Java constructor completion
jdtls appends the call or body to filterText (`String(${0})`); matching
on the label instead lets typing `String` rank `String` above
`StringBuilder` and the other types sharing its sort text.
* fix(editor): List identical completion items once
kotlin-language-server repeats a class once per classpath entry declaring
it, so `String()` and `String` were listed three times each.
* fix(editor): Keep the internal cancellation message out of the UI text catalog

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.
