Is there a way that we can add information to current listings such as a view counter, and maybe an option for prospective buyers to leave feedback such as if they feel the price is too high, or the listing needs more pictures? Some of my listings aren't selling and I have no idea if I'm pricing them too high or if they just aren't getting enough visibility/the games aren't as highly sought after as the prices would suggest.

Sort collection by all non-CIB items

I see Heritage Auction listings for some games.  Can you input this data automatically, or at a minimum, provide a way for us to report Heritage Auction results in the same way that we can with eBay listings?

Interested in expanding on your Pokemon Pricing and Collecting into the Magic! The Gathering series. or at least to be able to add to the collection to help keep track of your owned cards and manage and sell them through your site.

I play pokemon so I don't only have one card of a lot of my collection, adding 17 bulbasaur base cards with the standard "add another copy' is time consuming. A quantity input box would be so helpful!

Some of the games in my collection I need just the box or just the manual to complete, would be nice if in the marketplace there was an “include only” filter like in my collection to view listings for a specific combination of box, manual, or game.

It would be nice to have a feature in the market place to filter listings by loose, game/manual, box, CIB, New

Currently the historical chart defaults to loose, which is great for cartridges, but for any disc based system it'd be cool if it defaulted to CIB, since the first thing I always do is toggle to that.
