#uwsm is absolutely lovely. Finally, a good integration of sway into the systemd system. This makes sway *so* much less of a pain, holy crap. Also, graphical apps and so on go into their own cgroups separate from the compositor!
This was quite a bit of configuring I had to do. But the best thing is, thanks to #NixOS, I could have booted back into a working system at any time – and once I had it all set up on my laptop, I just had to apply it on my desktop and everything works just the same.
