Meanwhile, Amiga 1000 Workbench (also released in 1985) not only had application switching, even when full screen, they had desktop screen switching where each screen can be different resolution / colour depth.

The key combo was Amiga-M to send window to back of stack, and cycle windows.
BTW = Amiga had preemptive multitasking
But the world decided to ignore the Amiga and focus on MsDOS and black and white MacOS.
Yes, and absolutely ghastly screen artifacting when doing so which would have had Steve Jobs smashing the screen with a chair.
(my favourite Amiga game was Obliterator, but I hated the screen appearances one had to go through to get it running if one had been doing some sort of graphical work)
Also, only pixel fonts --- but the Apple Mac at that time was outsourcing its own vector font usage to the much faster processor in the Apple LaserWriter.
Lots of TV stations using Amigas for screen graphics though.
