Relocate region from console search to optional button
Having separate filters for regions is redundant, for example; playstation 4, pal playstation 4, and jp playstation 4. It would be better to have everything under one console, and then have optional buttons that specify region underneath.
This would shorten the search bar list considerably, while not removing any functions.
Also, when adding a game to your collection, it would be easier to find the game you're looking for first, and then mark which region you have it in. I have several examples of instances where I only found my game with another region code, since my regions version of that game had not been added to PriceChartings database

Ability to search own collection only
instead of just filtering by console or alphabetically. have a search box that can search all of our own collection. i.e. searching for dragon quest, would return a list of all dragon quest games in my collection regardless of console

When browsing games to buy, have an icon to show what you have in your collection already so you aren't buying duplicates.
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"

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

Adding Telepods (Angry Birds Toys-to-life) 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.

Allow sellers to block buyers
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 Game Wave to the list of systems
I would like to have the Game Wave Console add to the site.

We've added backend support for GameWave now. Users can add any games or systems to the site now.

Bug: Show systems only in collection
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.
