Allowing me to sort my collection by popularity to help me know what could sell faster or what might take me longer to sell.

There should be an easier way to add comic runs than one at a time. For example if I have JLA issues 1–40 it would be great if I could add them all at once and identify what folder in my collection I would like them all to be. 

It would be great to have card rarity (Common, Uncommon, Rare, Mythic) as a column in the lists ... being able to sort and filter on those would be of particular benefit.

It would be ideal if we could have the ability to select/create folders when we do large item imports. For example I am wanting to import large number of Magic the Gathering cards, talking 10,000+, into the My Collection. Ideally I would like to create a folder for each set that way I can keep things together more. That or if there was a way to view or filter collections by the set. 

Hi, 
I was trying to contribute and add the Samsung Korean Megadrive (https://segaretro.org/Mega_Drive_consoles_in_South_Korea), but none of the regions fit, so none of the following checkboxes are filled.
Could we add a Korean region?
Thanks.

Just wondering if I'm doing something wrong, I noticed my purchases on some collectables are not showing up on the site yet. Do you guys know how often ebay sales data is refreshed? Thanks!

I believe this is a bug. I am an Android user with the web app. When I try to search by "Take/Upload Photo", the only option I have is to upload a photo. It would be nice to take a photo directly with the app.

Would be nice to add my video game vinyl records to my collection list.
