<span class="badge badge-small">Sep 23, 2026</span>

## Build 210

<span class="badge badge-small">Sep 17, 2026</span>

- Various performance improvements
- Minor UI improvements to search in project
- Added move cursor right at end of line to unfold if folded
- Changed `Cmd + 1 2 3 ...` to navigate between open tabs when many selected tabs, otherwise normal behaviour
- Added default keybinding `Cmd + ;` for `previous_tab`, and `Cmd + '` for `next_tab`.
These can also be used to navigate between any selected tabs.
- Changed inline chat to use `>` as symbol for prompt line (similar to `%` for inline shell).
This can be changed in config `inline_chat_symbol`.
Removed prefix on chat responses.
This change also brings inline chat under `Inline command`, so uses `Cmd + Shift + Return` instead of `Cmd + K` as default.
- Added pixel-by-pixel momentum-based smooth scrolling.
This is a large rewrite of scrolling behaviour for editor, minimap, and scrollbars, so please report any issues found.
- Added recently opened files to dock icon menu
- Added click on line info label to switch to word count, this replaces config option `show_word_count`
- Added short easing animation to pane open and close

- Replaced custom title bar with macOS native title bar.
This change also replaces the buffer/ tab list in title with native title bar file controls.
This included a large rewrite of the buffer management, so please report any issues found.
