What would be super to see is a listing that could be easily downloaded of everything the designer has created. Then when someone purchased products from them the purchaser could check it off. This would save me hours of looking through files and folders to see if the particular kit, etc had already been purchased. A list or an Excel type file would be easy enough to maintain. Then it could be updated when there were more products added. This probably could be done from the database that is probably already in place that causes the store and shopping cart to function.
Also, it would be extremely helpful if the designer chose to use the same file identifying name or letters for each of their products so it would be easy to find everything that had been purchased or created by them.
