At first I had a lot of trouble making sense of the UI, but now I think it's pretty neat. It's essentially the final form of the Material Design idea, where each app is a Card like a physical deck of playing cards, and you get to arrange them by dragging them around, with the important and intentional limitation that they snap into one of a finite number of arrangements. How do you undo a splitscreen or tabbed layout, though? The rest is just mockups at this point, I hope; for example, the control center is pretty rough: presumably the user knows their own location, and when they're looking at this screen, they probably don't care; the full date is hidden whereas most people forget today's date much more often than they forget their own location; there is no obvious way to do auto-brightness, the negative space is in all the wrong places; etc.
