When in the Music Store home, clicking on the little dots in the center of each of the areas' title bars (i.e. "New Releases," "Exclusive Tracks," "Staff Favorites," etc.) jumps to that page in the scrolling collection (similar to if you click on the left and right blue arrows, but better). For instance, if there are four pages of "New Releases," and you want to get to the third page quickly, just click the third dot from the left in the center of the title bar. While this might not be a great time saver today, if there are eventually tens of pages in any of these categories, having a quick "jump to page" feature will be a real time saver.
I just discovered that today. Not revolutionary, but nifty.
