Search that thinks ahead
Looking Pretty - Yes, you can see the difference as soon you enter. It is a lot more easier to view the contents and looks pleasant too.
Getting organized - The much awaited folders option are available now. Interesting thing is it act as a tag too!!! I defintely love the drag & drop option.
