About that touch-scrolling, you can also grab the "applications" overview and drag it around. But if you try it, you notice that the dragging is paginated (you can't stop dragging between two pages of applications). This is while the interface lets you assume it's a continuous thing (with a scrollbar, icons split in half if they go over the border ...).
According to me, that's a design problem. If it is paginated, it should show one nice aligned grid with icons per page, and have pagination dots instead of a scrollbar. If it is continuous, you should be able to drag-scroll to a where you want (and not be bounded by the page boundaries).
