- LaTeX code folding: \begin/\end, sections, \if/\fi, comment blocks, braces
- Outline view: section hierarchy in sidebar with click-to-navigate
- Smart closing: auto-close \begin{env} with \end{env} on Enter, $...$ auto-pair, selection surround
- Math hover preview: tooltip when hovering over $...$ expressions
- Enhanced syntax highlighting: bolder commands, better color differentiation
- Fix compile error click: jump to line works for errors without explicit file path
- Semi-transparent active line + selection highlight layering

- Terminal now spawns in project sync directory so Claude Code can
  read/write .tex files
- Selection highlight uses semi-transparent color to layer above
  active line highlight
- External edits use diff-match-patch for minimal changes instead of
  full doc replace, preserving comment highlight positions
- Set connection state on project open so status bar shows Connected
- Remove cursor:pointer from comment highlights
