Nice! This is great that you're taking this on. I love the library, but definitely been frustrating not having consistent fixes and updates. Just leaving a comment here so I can watch for when this is merged and give your fork a shot. Thanks!

@jwoertink I've actually been maintaining this fork for ~9months starting with this PR here:

ssleptsov/ninja-keys#47

I've been using it in all of my personal sites.

This PR is just additional cleanup and scaffolding up an actual docs site with examples.

https://github.com/KonnorRogers/konnors-ninja-keys/blob/main/CHANGELOG.md#130

Starting at 1.3.0 has the changes I've been adding!

Feel free to open additional issues if there's anything else you'd like to see / you're missing / any bugs!

Sweet. I've been using my own fork, but I'll give yours a shot. Thanks!
