Seriously, so useful for floating window managers, it’s a simple and obvious form of transition, significantly better than what window managers have ended up at these days (if anything).

(Then I switched to i3, and more recently Sway. Not sure I’d appreciate wobbly windows in tiling window managers, though maybe with gaps (… which I’ve never understood the appeal of) it might be better.)

It warmed my soul. It's the only thing I really miss since switching to i3.
