Thanks, I'll take a look.

I'm already using MenuHammer[1] (menu system inspired by Spacemacs) and Spectacle.

But plan for a next year or two is to build custom ergo keyboard (r/ErgoMechKeyboards has a bunch of interesting stuff - I'm aiming for Corne or Iris) and then to customize keyboard layout + Hammerspoon to reduce mouse usage as much as possible. With various VIM plugins available for editors and Firefox (Tridactyl) I'm quite optimistic.
