On the fifth attempt, I was able to get the installer for #Fedora #Sway Atomic to succeed.
The default Sway experience was bad. At login, I was given one layout to select from the "??zz" layout. I'm not making up the name.
One logged in, the UI is keyboard driven, but there's no hint what the keybindings are. I managed to open a window by clicking on the bar, but there's close button on the window.
The #Fedora Sway Atomic team should take note of how #Regolith puts together a Sway remix.
Some things Regolith gets right:
1. When you first login, there's an overlay that shows you the keybindings.
2. The Regolith launcher is much nicer, including icons and tabs for various functions-- including looking up the keybindings.
