(many) apps keep running without windows — all you closed was the last open window. cmd-~ switches between windows within a running app. this has been the case since the classic Mac days, & while it seems to drive those who come from Windows bonkers, long-term Mac users (at least all I've known) appreciate this small aspect of macOS as it makes a clear distinction between apps & windows. newer apps (some from Apple) which break this model are still maddening to use.

That's fine, but I do not want to tab into an app whose last windows I have purposely closed. I closed it so I have a cleaner slate of apps to work with. If chrome is closed, it should not show up until I open it again. Not just windows but also linux make much more sense in that regard.

It's annoying because the x button on the windows is now a completely useless widget to me, and I have to close apps via cmd+q instead. It's even more annoying that I can't actually close Finder, even though I'm using a different filebrowser.
