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?
You might have some GUI nonsense happen, but for the most part you’ll be okay. I have exclusively used i3 for my Linux stuff over the past few years and have only run into a few problems with misc apps
