Changelog

b210

Sep 17, 2026

• 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
• Added short easing animation to dialogs that change position or size dynamically
• Added tab multi-select behavior to the Buffer Explorer dialog, Cmd + B, as well as drag tab outside window to open in new window.
• 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.
