Another benefit is how sick it looks (In my opinion). Anyone looking would be interested.
And then I use workspaces for different groups of windows, i.e. messaging apps, the browser, and different projects all go on different workspaces.
I use xmonad so I'm well used to tiling, I just don't get why you would want to have a view into only half of a window.
Besides, when it's something like runtime logs in a terminal, I sometimes keep the terminal maximized (to avoid line wrapping), but only leave it peeking out, so that I can switch to it if I notice something strange in the left side of the output.
I think most tilling WMs fails to realize how annoying windows that keep changing size are. If they do, the entire concept of automatic tiling seems way less useful.
A code editor does not need a terminal, because everyone already has a terminal that is not restricted into one IDE window. Do you run tmux inside your IDE's terminal? Do you never use any other terminal? You shift the goalpost to video editing, what is the specific double-67% requirement now?
Did I not make a generalization that software UI often involve multiple panels in a single window? Just quit chery-picking arguments and think about that, and the fact that PaperWM exists, and again how anoying automatically resizing windows are.
Hey turns out I did say things other than terminal and video editor!
Floating WMs also exist, and all kind of unergonomic setups exists, I'm just questioning your reasoning.
