If you have a low-resource computer, one with a small screen like some laptops, or are even someone just looking for something different to try, a tiling window manager could be a good option.
They’re not for everybody, but then they’re not just for command-line commandos either. I’m a keyboard guy, I like using keyboard shortcuts and keeping my hands on the keyboard as much as possible. Besides, I suck at touch typing and reaching for the mouse constantly just throws me all out of whack when I go back to the keyboard. It’s one of the reasons I was a KDE user for such a long time. KDE’s Plasma Desktop is probably the most keyboard customizable desktop environment out there. Plasma had some quirks though; there were bugs and oddities that annoyed me quite often. So I found myself in the ‘looking for something different’ category.
