Do you not often quickly look between files? If so, odds are you're using tiles within tmux, vim, emacs, vscode, or something.

I use kakoune, which has a client/server architecture. Each kak instance I open within a project connects to the same server, so it is natural for me to use my WM (niri) to tile my terminals, instead of having something like tmux or the editor do the tiling for me. I don't want to bother with more than one layer of WM, where separate layers don't mix.
