Yeah, that UI looks like it could perhaps use some improvement, it's a bit on the 80's side (which isn't a bad thing in itself, I mean, I like my emacs, but I only use keyboard there unless I forget the bindings, which is not totally everyday).

Maybe they can re-write it in rust and add like help tooltips and some confirmation popups? Like "You're about to do this X with Y to W. Confirm?"
