> Task switching is.. not good? I don't get window previews I can switch through when I hover over the dock, but I do on Linux. That just sounds like being accustomed to one way of switching tasks, honestly. If I want previews, I use Expose (three-finger swipe up/down or ctrl-up/down).

The app switching behaviour is really infuriating. Selecting a window and having all the app’s windows come to the fore, obscuring the window from another app is still annoying, 20 years on. And then when you full-screen a window, switch to another app for a moment, and then you can’t find it without delving into the ‘window‘ menu. First world problems. But daily annoyances.
