I don't understand why multitasking works the way it does. Why can't I drag something from the app drawer? Why can't I drag from the app drawer, open the multitask view, open an app there and drop it next to that? Why does it have to be from the dock? What's the expected process? Am I supposed to open the app, then open the next app, then drag the last app from the recent app part of the dock? How tedious. I feel like nobody at Apple actually uses the multitasking part of iPadOS, because if I wanted something intuitive and simple and easy to use, it wouldn't look anything like it does now.
