• Custom line iterator code for file loading, because rust's built-in one only recognizes LF and CRLF.

• Line number display

• File opening by entering path

• UI that wraps editors, for split view.

• Persistent infinite undo

• "Projects"

• Clean up text buffer interface:

  • Editing (these are undoable): //- insert_text //- remove_text_before //- remove_text_after //- move_text
  • Undo functionality: //- Undo //- Redo
    • Op section begin (for delimiting composite edit operations)
    • Op section end
  • Info: //- grapheme_count //- line_count
  • Position conversions: //- index -> line_col //- line_col -> index //- index -> vis_2d //- vis_2d -> index
  • Reading text:
    • grapheme at index (includes visual width in return)
    • Bidirectional grapheme iterator (useful for search code, etc.)
    • Bidirectional ine iterator (useful for display code)
