I started working on Flyaway with the intention of becoming familiar with Wayland, its protocols and extensions, and the wlroots library. Instead, I ended up genuinely liking all three.
see it playing nicer with nvidia
This may seem like a small nitpick, but the way you phrased this is backwards. Keep in mind that the problems with wayland on Nvidia cards is squarely to blame on Nvidia. Nvidia is finally playing nice with wayland, not the other way around.
