For a while I used XMonad (as a window manager) together with Xfce (as a desktop environment). It had its rough edges, but I really liked the experience. I could easily fit my windows on the screen the way I wanted to, while still getting the integration of a well-designed desktop environment.

Alas, I had to drop this setup on moving to Wayland. And I can’t get it back easily, because Wayland compositors generally don’t allow for their window managers to be swapped out. I now use Sway WM, which is perfectly acceptable… but I still miss my tiling desktop environment.
