Oh, I know. I use sway — and greatly miss alt-tab (windows-style alt-tab), when I do.
Not linux-primary right now.
I can remember my linux-style stacking commands in order to try it.
But I would want to fix my alt-tab at some point.
Note: my sway (or mac) usage is basically two vertical windows or stacks of panes on a laptop screen. So a pretty simple setup.
