I've really appreciated running i3 within gnome-flashback. I keep hitting things that just work, that I didn't even realize I wanted. I hit the pause/mute button on my headphones when watching youtube and it paused… Things like ssh agents, hotplugging monitors and having it remember your preferred config, the main gnome settings GUI, the compose key, etc… I'm just not interested in reinventing all that, even though each individual step is usually not hard.

I'm glad to see Regolith is making a DE with Sway. One day I'll migrate from i3 and I may let Regolith give me a DE.
