Thanks for the pointer. I am getting more and more frustrated with Vim (and neovim is not what I am looking for) and looking for alternatives.
I did try "vis" a while ago and it was alright but not quite there yet. And it was a bit too "sickness" for my taste, e.g. requires shell scripts for completion to ":open".
I do intend to try it again some time but I'll also give kakoune a go.
