To switch to another window, we already had Command-Tab, Mission Control, Expose (now part of Mission Control if I understand correctly), and also clicking on the icons in the Dock. And now we have Stage Manager. I had to use Windows 10 as my main workstation for a few weeks at work, and I'm starting to think windows management is – perhaps – one of the rare things Windows does better than macOS. But of course I should probably try Stage Manager before ranting about it here :)

This. It's unacceptable that macOS still doesn't support basic window management and users have to install Tiles/Spectacles/Magnet/etc.
