I have, as well as Amethyst. Yabai is what I've settled with, and it's absolutely usable for my work flow. I probably need to fiddle with it some more, but the thing with i3 is that most of the the default set up works great for me. Trying to emulate that in something else has been a pain.

Maybe I should just learn to be more flexible!

absolutely love amethyst! i wish I could long press a hotkey to remind me of my own hotkeys sometimes but as far as a non-linux tiling wm goes, this is the way.
