Earlier quoted context omitted.
Except for the lack of a proper fullscreen function...
Believe it or not, full screen apps are a Windows thing. Apple has added full screen app support only recently, and any Windows convert who has switched to macOS and has problems adapting to its UI has one thing in common: they haven’t let go of the idea that all apps need to use the whole screen at all times.
I read somewhere that the reason Apple finally added full-screen support to macOS (back then OS X), wasn't because of the Windows switchers. It was to get a bit more real estate out of the MacBook Air's small screen size.
