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.
Regarding the F16, Ukrainian pilots are going to start testing the Gripen as well, although that path is obviously far behind the F16s given the glacial pace of such developments...
