I am actually working on a project called vimgolf.ai, where I am looking at giving users the ability to practice these commands. Right now, only have a few levels, but looking at expanding to account for 80% of the commands used on a daily basis. If anybody's interested, please check out. Though please be aware at this time, the site does crash from time to time. Still working on scaling the nvim instances across nodes.
Hey! I saw your post on reddit a while ago! I think though that removing the sign in would definitely be nice for less bounce as others on reddit said. Otherwise i I think it's fun!
If you'd like to we can talk or mention eachother's project on our site to get a backlink and also to help noobs (like me, haha) go back and forth, because I think having a cheatsheet and somewhere to practice also could be fun and the audience might be interested in one-another! You can add me on Discord under "pici_csomi" if you want to talk :)
