When you move multiples (say, a stack) of items around in inventory by dragging, you now get the "multiples" version icon of the those items (e.g., four milks, a bunch of herbs, a pile of meat, etc.).
It's cute, BUT it makes it much harder to accurately target inventory slots. And it's weird that the view you begin dragging turns into another view as you drag.
I think this is an improvement that isn't really an improvement. It was worth trying, but it I don't think it really works.
