This workflow is even easier on a Tiling WM.

These days I use niri which at its core, is just Alt-Tab blown up as your actual desktop.

Seconding Niri, it's easier to configure compared to other Tiling WMs and has good out of the box defaults.

Though you'll have to fiddle a bit with stuff like waybar, fuzzel and xwayland-satellite. But once you've configured that stuff you won't have to fiddle with it non-stop.

I'm currently running it on Fedora, to be clear.

The point is I don’t need any wm for this workflow. It just works on any box regardless of OS.
