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
oin 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?
