I removed some of the stuff I don't use because the compiler complained about it after I removed the mappings and I was sufficiently bored that day :-) Being bored was actually the reason I was even looking at dwm in the first place, and somewhat to my own surprise it seems to have stuck.

I don't like dealing with multiple things on my screen (from the WM, tmux panes, Vim windows, whatnot) and like focusing on one thing, so I've had a pretty simple and straightforward "full screen all the things" workflow for years (well before I used dwm) which doesn't demand much from my WM. I mostly use tags/workspaces, tmux windows, and Vim tabs to switch between things.
