- Add new "Autocomplete" option On ↲ which enables the return key ↲ to always trigger completion, instead of only in certain contexts. The default remains On ↹ using tab to complete.
- Accept either return key or tab key for completion when triggered manually with ctrl space. This also works this way after the completion menu has been interacted with.
- Improve scroll bar mouse interaction. Scroll bars are easier/wider to grab, they visibly expand to 2x width & are highlighted when hovering over them.
- Add missing CJK support in code branch menu.
- Update code dependencies and compile with rust 1.55.
