As I look to grow my collection and some listings are time sensitive, it would be nice to have an icon of some sort that shows what you have in your collection already. That way we can avoid purchasing duplicates. 

Icons for "loose, cib, new ,etc"

It would be great to add a Shopify App that would allow inventory to by synced/listed to the Price Charting Marketplace. 

Add the vtech smile console and games to the site

It would be really nice if the Telepods (which are Angry Birds' Toys-to-life line of toys) were added to the database. Telepods were created for mobile games such as Angry Birds Star Wars 2, Angry Birds Go, Angry Birds Stella and Angry Birds Transformers. Instead of being NFC figures like amiibos and Skylanders for example, Telepods instead use a tiny QR code on the bottom of each figurines that needs to be scanned by the phone to be summoned in the games.

Some buyers don't read the description and then leave negative feedback because they didn't get what they expected. They also email and act like a smart ass and try to make an argument, then two days later, they purchase something else. Then I have to cancel, giving them the opportunity to leave negative feedback once again.

Add Timex Sinclair computer systems (ie TS-1000) and games.

I would like to have the Game Wave Console add to the site.

With the addition of the sports cards "systems", it is now an annoyance to have to scroll down past all of the 20th century sports cards categories (like 1972 Topps, 1994 Fleer, etc), this takes up about half of the list of systems when I'm scrolling through the systems in my collection, even though I don't have anything for that system in the collection.

Please filter the collection's systems list to systems only in collection.

Add ability to batch add games in bulk to your collection by scanning the box barcode.
