For digital items where a limited number of downloads are available, it would be nice if the listing page showed that number.  This is helpful for the creator in a variety of ways.  Currently, to see how a piece is performing, we have to go into the edit page to see how many sales there have been.  This is an added step that could take time if a person is trying to check up on multiple downloads.

Secondly, buyers are more likely to buy an item if they know there's limited availability.  If they see that there are only three available, that could be all it takes to get them to click.
