Until #Gentoo portage catches up with the packages needed for #StumpWM to run without crashing, I think I'll give #QTile a go. Can't do the keyboard shortcut things I want, but neither can most other WM or DEs.
Should be very helpful with the new 3440x1440 monitor arriving tomorrow. Large fonts AND two windows next to each other. Sounds great; I can't wait to experience it. (Upgrading from 1920x1080.)
