Add the origin of promotional TCG cards
For example, for Pokemon card Charmander #44, the card was obtainable by purchasing the Obsidian Flames Elite Trainer Box. For Dondozo #12, the card was included with a checkout lane booster. It would be helpful for locating which product to buy to obtain the promo if said product is still available. Thanks!
On List Value tool, add option to select condition
The tool is difficult to use because I sometimes forget what value those are based on (Item only vs CIB etc).
Itd be nice to have a top level condition selection. Then be able to adjust each line item to account for what is missing or not.
Export date purchased with Collection Export Tool
Export doesn't have date purchased but there is date entered which are 2 totally different things. I don't mind to have either both or at least replace date entered with date purchased as its the correct one.
"Add to lot" from lookup screen (comics)
We look up individual comics all the time, and sometimes they are part of a lot of a collection. It would be beneficial to have a button for "add to lot" available right on the main result/details screen for a book. (Like "+wishlist" and "+collection")
Yes, we can add them from the lot page. But if we are identifying by picture we get to that details page first, so it'd be beneficial to cut out the extra step of recording the title and issue and then moving to the lot page to add it.

Korean DS/Wii Games
I'm aware that there is an Asian English "region" for several consoles (PSP, PS3-5, PSVita, and Switch), however there are other consoles like the DS or the Wii with Korean games that are starting to show up on sites such as eBay. I think it would be really cool to see some of these games on this website.
Can Selling be Easier?
Is there a way where we can add to collection with detail and select a drop down to select if you want to sell, keep, undecided options? If you do sell a card, could it be removed from your collection.
Filter by console in the wishlist
For some time now, the wishlist no longer allows you (by default) to filter by console or game support, which is a bit annoying when you want to easily check the games you're looking for on a specific console. Is it possible to restore this option?
You can still filter wishlist by the set. You need to filter by category first. Then filter by set option will be available. Here is a screenshot of it.
