It would be nice to have separate listings for "world edition" Nintendo games, which are essentially ESRB versions of some Switch, 3DS, Wii and Wii U games specifically sold on middle-eastern and southeast asian markets. The game inside these versions is exactly the same as the NA counterparts, but due to the differences in the covers (which range from a small circle saying it's the world edition to a different cover art entirely in some rare occasions), the prices of these copies thend to be different from the actual north american games, especially for sealed copies (e.g. Mario & Luigi Paper Jam, sealed world edition copies are easily found for ~$40, meanwhile actual NA copies go for upwards of $100). 

I'm not sure if it's feasible since these games usually have the same UPC and many ebay listings don't mention that they're the world edition version in the title (sometimes it says "middle east version" or something like that), but it would be a nice feature to have.

Add non holo or add holo option, when a Pokemon card has a holo and reverse holo. There are very much prices of cards where the price looks higher because non holo cards prices are taken by the sells of the holo's or special editions.

I would like to see this category added.  I have quite a few of these cartridges and would like the ability to track them along with my other systems.

It would be nice to have a tab in your collection for incomplete games. It would be easier to try to complete them.

The default add to collection in one click for cards is set to PSA 7. Would like a setting to change the default to ungraded.

What a useless piece of shit programming. I "import" line by line of text, only for the system to recognize that I uploaded 44 items without adding them to my own collection. How does that even happen? Why don't we have the ability to upload tab separated values or .csv? WHAT YEAR IS IT?

I am not going to type in a game name, click on the appropriate name (which is wrong about 15% of the time, causing mismatched data), click add to collection, click details, click on cib from dropdown, then FINALLY click on add. I have 2500 items to add...that is a ludicrous waste of time! FIX THE COLLECTION IMPORT
