- [x] navigation control/actions: seek occurrence of character ('f' forwards, 'F' backwards by default; allow e.g. `2f` for seeking second occurrence instead of first).
- [x] buffer ux improvement: enable mouse scrolling sideways so longer lines are easier to follow and read (e.g. in case they extend beyond the width of the buffer view).
- [ ] buffer ux improvement: add toggleable word wrap (no keybinding by default).
- [ ] diff view: add character-wise change highlight (enabled by default).
- [ ] diff view: change diff view modes; choose between split and unified diff view (split by default).
- [ ] diff view: for split view, change split orientation (left/right vs above/below) - left/right by default.
- [ ] diff view: github integration (code review) - add comments on a pr, add review comments at specific lines of files, request changes, approve pr, etc.
- [ ] diff view: local review comments (same features as for github reviews) that allows review of local changes to deliver specific reviews to ai agents used for coding.
    - design question: would this require a server that the agent can interact with, or would local review files be fine? don't want to use server client stuff, if it would be easier and better to just use local files.
