Thanks for the config it looks interesting and quite mature, the possibility of sharing such kind of has me on board.
Incidentally I was coming from i3 (xmonad before but wanted something I could switch over to wayland where I could watch video like its 1995). Never in love with configuring all my own task bar, power management, disk mounting, screenshot program, rubbish task launcher with no icons, etc. but did it anyway for the sake of beautiful ceramic tiles... I've been playing with pop shell gnome extension for creature comforts, which via dconf plugin of home manager actually seems text configurable. Not that I've done it yet.
See you are using sway, ever considered going IKEA with gnome?
