That's a really interesting answer - it all makes sense that those things can be irritating, and also why I had no idea about them:

For years I have had my applications and windows (IDE, tabbed console, browser(s)) set up in fixed positions. I rarely switch between them in a way which isn't a keyboard shortcut (99% command-tab) or involves the mouse anyway (for testing, or video calls). I never normally move windows between screens or anything like that in my workflow.

In the good and very old days I literally just had emacs maximised and that was it, all day long 😇

I guess I got lucky in a sense - that not needing functionality meant I wasn't affected by it being missing, but it might partly be a positive side effect of desiring simplicity and less from the WM so I can focus on my own things.
