Add Interpreter (creating a virtualenv), the Python packages list and pip install/uninstall, Settings › Git › Test, JVM listen-mode debugging and Create Patch › Save to file failed with "no project is open in this window", or ran without the project. Their commands passed an empty window label to ops that resolve the calling window's project. They now pass the real window label, as the other project-scoped commands do. A sweep of every command that passes an empty label found exactly these seven ops using it: `sdk_locate_tools`, `sdk_python_create_venv`, `sdk_python_packages`, `sdk_python_pip`, `vcs_git_version`, `debug_listen_for_jvm` and `vcs_write_patch`. Without the window, the last one skipped the project's disk sync, so a patch saved inside the project showed up as an external change. Fixes #955.

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.
