I have just discovered the kakoune editor, and I am enamored. This will likely end badly. https://github.com/mawww/kakoune

I feel the same

right?

I mean, it really seems to be "vim done better" and the design choices are kind of amazing. I'm worried about ergonomics a bit.

One thing for sure, though, the idea that tmux should be the thing controlling the panes seems good to me. I think I'm going to do that. I can't really think of what I'd lose, except for minor things that can be fixed.

Building a REPL connection is slow.

(above means one file per instance of Vim)

The only other thing I can think of as a drawback is that auto-complete cannot be wider than the buffer.

It seems to be client/server so that state would be shared between windows?

@clashthebunny at this point, I only have a vague sense of how it works, but I think each instance is a server.

I guess each server is named. Check out how they focus a pane 😄 https://github.com/mawww/kakoune/blob/master/rc/base/tmux.kak#L41-L50
