i3 4.18
I guess tiling window managers should be considered more of a specialized niche tool, and in that it is commendable that i3 does such a good job of it. I do really admire it for being so light-weight on resources compared to a lot of the other more popular WMs.I say a niche tool because I've never really understood why someone would prefer a Window Manager that places a lot of constraints than one that  lets you controls / customize the windows as you please and is thus "freer".I guess it can seem useful for, say, multiple terminal windows. But would suck for a scenario where you have to open different kinds of applications like a browser, file manager, video converter, movie player, terminal  etc. etc. (just citing all the apps I have open now and am multi-tasking with) where the ability to stack them would prove to be more productive for the user.That even control freaks like Apple, who like to think only they know what's best for their consumers, doesn't use a tiling only WM in their OS is telling. Even Microsoft switched from a tiling WM from Windows 2.0 on wards and has stuck to it (Source: https://en.wikipedia.org/wiki/Tiling_window_manager ).
