Would love to see which games are available and how many of them there are in the Marketplace currently straight from my Wishlist screen. Either add a column with that information ('Currently Available') or add a sorting option for 'See what games are available'. 

I have a massive spreadsheet with the cost of each item which I would like to automatically import when importing bulk items.  It's painstaking to have to go in and manually enter the cost of each and every item after a bulk import.

Hi! 

I have made some research and collect some base data of this part of a game market and could contribute the initial info with series, numbers, titles of a card. 

It would be nice to have more accurate pricing by having separate sections in addition to loose, cib, manual, box, new, and graded, there should also be 2 new sections for loose game plus the box and loose game plus the manual. Many sales are a combination of those two and they distort the actual average price of both the loose and cib sections.

Create category for Tandy 1000, 2000, 3000 series of computers.  And Tandyvision

The mostly forgotten, and very poorly marketed, handheld from the early 1990's the went silently away as stealthily as it appeared. Most fellow collector's I communicate with have never heard of this system, a testament to just how obscure the thing is, but it does exist. To those who know of it, it is a highly desirable handheld to own.

Be able to search your collection to see which games you have extra copies of in the event you decide to trade games.

It would be really nice to order my long wishlist by priority, or what I want to buy next, and so on. It would help me to be a lot more organized in the long run if I could move my wishlist items around and put certain ones above others.

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

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
