I only tried a tiling WM for a few days several years ago. I am ok using the terminal but not everything can be done easily there. In the screenshots of people setups, there are always fancy terminals. Are tiling WM good also for other GUI a part from terminals?
I use a tiling WM for everything. Libreoffice, games, Firefox/Chromium, file managers, etc. It all works and it is a great way to handle multiple monitors.
