Oh, I’ve tried every tiling WM at one point or another, but it’s never taken hold. And I’ve used no end of Tmux over the years, but never really bothered with the shortcuts in those either, so doing it for a WM never took.
Everyone that uses one raves about it, but I’ve never found the fit, even with the amount of windows I keep open at any given time. If I get really ambitious I’ll use Plasma’s Meta-T to set up tiles, then promptly forget about it.
