What proper window manager shows tab group list at the top of the current app window and allows shortcuts/mouse to reorder the list and also allows moving a tab outside of this list to another tab group?
Sway and i3. But when a WM does it, you can mix different apps in the same tab group, and your tab key binds can be the same as your WM key binds. You don’t have to remember alt+h for tabs, win+h for windows, etc.
But I’m just busting your chops, don’t listen to me. I don’t even use i3/Sway, or use tabs at all. Everyone has their own workflow that works best for them.
But you do have to run a proper window manager so you don’t have to require tab support in every single app. ;)
