The could definitely do with cutting down some of the empty space and the “border stacking” problem that feels like old fashioned “div padding” stacking when doing html, though I feel like that trend started a few versions back in the flat ui design. Interestingly the iPhone version of Liquid Glass seems to have much less “extra” white space than the Mac version of it, which seems backwards because the iPhone should need/want more for larger touch targets. Or maybe it’s just less noticeable because it needs those large touch targets but also lives on a smaller screen.
