We currently have cbvike, which has one major drawback - it doesn't support any kind of vimrc. And, for example, I really dislike using the <esc> key - I'd rather use ctrl+[ or even set up jk for this.
Unfortunately, I won't have time to code this, too many . If you wish to, here's what I offer
1) Testing - I'll be doing a medium-sized C project next 2 months, so I'll have a lot of opportunities to test this.
2) Packaging - I already packaged cbvike, so all the changes will hit the AUR.
Are you willing to take this up?
