Currently, when you pull up the main page for the swap, you see a summary of your activities such as # of items bought, # sold, etc. But, the actual 'Sold items' page doesn't give that information. I think it would be great if the sold items page showed the total number of items that you have sold in the swap. Other 'nice to have' options would be to list the sold items by item. While the current method of listing by 'Buyer' helps fill orders, a list by item would help keep track of just how many are needed of each item.
Just my 2 cents!
