Description

There's a bunch of places we could improve performance.

  • Don't redraw during repeated insertions
  • Don't redraw for every cursor in multicursor
  • Don't redraw during undo
  • Don't redraw during macros
  • There seems to be a delay in commands like o in switching from normal mode to insert mode. I'm not sure whether this is a visual issue or an actual delay.
  • Offload more things to neovim?
