interest in squishmallow trading card prices

On my folders, I recently emptied a folder to make way for a different but it still has a listed value and says there are still cards under the Value, Cost, Profit, and Count. However, where it displays cards it shows there are none to add or delete. Any way I can fix this error as to not inflate my collection's price?

add this game

I would love a feature where you can hit a button and it picks me a game from my collection at random. In case in stuck on what to play or forgot that I owned it.

I have goosebumps cards made by topps that do not fall into any current category

It would be grate to have Korean card prices and Sets ( Pokemon, One Piece, Yu-Gi-Oh) since they are growing in popularity.

Thanks.

I have many cards that cannot be found when snapping a pic. They are from different CCG's that do not have a selection in your system, like vs. System, Rage, Blood Wars, Spellfire, LOTR, Red Zone, Top of the Order, NetRunner, etc.

When entering the price paid for a unit, add an option to select which currency this price is for. When toggling between the display currency on the main website, the price paid would change to the displayed currency.

Example: I buy a game in Japan for 1000 yen. I could put 1000 yen into the "price you paid" section. When I return to my collection, the price will display in USD if USD is selected as the current display currency.
