UI designers got it right with a taskbar on the bottom and widgets to let you know what you have open at a glance without having to move the mouse across the screen or press buttons. For a multi-application PC desktop thats the right model. Not for phones ofc, they need a different model. Trying to force the phone model on the desktop PC model just doesnt make sense, not now, not then, not ever.

edit: grammar, also Cinnamon fixes these issues thankfully.
