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?
non-tiling window managers can also have different workspaces, or even DEs such as KDE Plasma. IIRC even Windows has those (although with inconvenient keybindings imo)
I think they’re talking about the tandem of tiling and workspaces, as usually you can customize your tiling per-workspace. Some TWMs have tags instead of workspaces, making it even better.
