With a simmering case of emacs chord key induced RSI I recently tried to make the switch to vim. The big thing I missed was magit, vim's port left me wanting, and the other tools just seemed like git cli embellishments. Just when I thought I was out, magit drew me back in.
Anyway, the screenshots from the OP make this project look like a very worthwhile undertaking. I can see why, perhaps frustratingly for the present project's author, this provoked a discussion on magit.
