Please add the ability to sort my views and favorites. It would be useful to see how popular or unpopular listings are.
To add to this add the number of sales and the number of renewals. If I renewed an item 8 times with no sales I should probably make a change.
Number of sales and renewals would be great also! Etsy just removed the snapshot of this info from the listing page so now it's really painful to look at this info!
