Probably seems weird to you, but I've never got on with the Windows UI. There's too many things that steal focus. I've been XFCE for too many years now, but it doesn't change significantly that I find I have to invest time learning what's changed. There used to be a 'tile windows' since windows 2.0 or something like that, but it did just that, splatted the windows to take up all the space. One thing I like about X11…
I rarely get focus stolen on Windows 10. They now make it very difficult for applications to do this (see the allowed conditions here: https://learn.microsoft.com/en-us/windows/win32/api/winuser/... ). In contrast, focus stealing is a way of life on XFCE, and I just have to put up with it. The settings they recommend to fix it don't actually help.
I am baffled as to how that has been allowed to go on so long. It makes Office a trainwreck usability wise.
