Interesting link! I type Colemak and pretty much gave up on Vim after trying to remap so many keys. This project didn't exist back when I gave up on learning Vim.
that project did not exist since i switched to colemak only recently, and that made my evil-mode setup (vim editing on top of emacs) completely unusable for me, which is why i started this project.
for a similar vim-based implementation (which served as inspiration for my remappings), see https://github.com/ohjames/colemak
