I can't judge for the patch in detail, but looks rather sane to me.

It is the same, just with current commit id / rev -> i could not wait, till one of the other one is maintained (and merged).

Thanks for this! Testing it out, it all seems to work, however the default keybindings seem to be missing for a bunch of things (like super-m for maximize). Seems like scripts/configure.sh needs to be run as well, or something like it.

@jsravn I set them up manually using home-manager's dconf module (they also include some tweaks):
