Agreed that apps forget where they were, or end up on the main screen instead of the attached one.

Rectangle deals with a lot of that with key shortcuts.

I don't love MacOS, but I don't hate it. I have a bunch of extra utilities like Rectangle, BarTender, MonitorControl, Karabiner-Elements, that make things better.

I use MacPorts so when I open a terminal, I get a Unix/Linux environment.

Things I miss from Linux/X-11, primarily middle button copy/paste, and being able to run an X-11 app remotely over LAN/WAN. But a lot of that is configurable with terminals like iTerm2.
