one more suggestion for Gallery albums

This suggestion has been made before, but I think it's a very important one.

I think it would be great if one could drag-and-drop items in a Gallery album to manually change their display order when needed.  If one wants to display material following a certain narrative (say, in a Gallery album associated with an Article or Blog post) to my mind it would be imperative to be able to order images to follow that presentation of information.  Sometimes ordering by upload date, title, etc. just isn't good enough.
