Since the early days of iOS, the Dock has been nothing more than a tray on which you could place frequently-used apps so that they’d be within reach no matter what page of your home screen you were currently viewing. With iOS 11 on iPad, the Dock is entirely different, and this means your approach to what apps you put in the Dock should be different too. ∞
iOS 11 on the iPad is a complete game-changer: because of the dock, because of drag-and-drop, and because of the Files app. iPad or computer? The line is completely blurred now.
