If they could implement the client/server architecture of kakoune, then this would really best editor (for me). It's a shame each editor implements a different subset of all the features I like and I'm always choosing between them.
Edit: Looks like there's an issue for tabs: https://github.com/helix-editor/helix/issues/2295 , doesn't have too much traction. I hope someone picks it up, unfortunately my rust sucks far too much to get it done in any reasonable amount of time.
