I tried for months to go vanilla and get my head around the features. But why, why do fullscreen windows create their own space when I want them to exist within a space? Why can't I briefly bring up Finder on top of my fullscreen window? Why are there lengthy animations to switch between spaces? Why do CMD+Tab and CMD+` have a million special rules for which windows they select? Why is there no way perfectly position more than two apps next to each other? Why are apps in splitscreen married to each other? Why can't I easily swap one of them? Why are some window operations keyboard-exclusive, while others can only be performed with the mouse?
There has got to be a perfect workflow where all this makes sense. Otherwise, they wouldn't build it like that? Right?
