Pull request overview
This PR tweaks the chat input toolbar’s responsive behavior so dropdown action items (session/mode/model pickers) keep their text labels visible at narrower editor widths by lowering the “icons-only” threshold.
Changes:
- Adjusted the width breakpoint for
onlyShowIconsForDefaultActionsfrom 650px to 400px.
When the chat input is narrow (<250px), hide chevrons on mode, session target, model, and workspace pickers. Mode and session target pickers collapse to centered 22x22 icon-only buttons matching the add-context button size. Update actionMinWidth to 22 and toolbar gap to 4px.
