I have not.

I've considered keyboard-driven WMs before, but have thus far gotten by using regular WMs with a few custom keybinds for window sizing, movement, and monitor placement.

As long as you have an automated algorithm for the basic layout, it works pretty well.

I still have to contendb with apps that don't offer the shortcuts I want, though, and that's when Shortcat is very handy.
