Starting to import some PC games that were only released in Japan, so adding them as NTSC PC games feels a little wrong. Also JP games have a few PC variants (i.e. PC-88/98, Windows, etc.) so a distinction for those would be nice

Add set to other TCGCard 

I think it would be great to add your gameplay status on each game with a drop down menu to that has (in progress, stopped playing, completed game, 100 % the game) just for an ideas.  
I know I would love to have that incorporated into my collection so I know it can plan what’s in my list of next to play. 

maybe a section to add playlist of games as well. 

Just food for thought. 

for example i'm organizing my pokemon cards by rarity (common, uncommon, rare ect)

I would like to be able to select a specific grade/grader for cards I have in my Wishlist so that I can see the current price for the specific version of each card that I am interested all in one place without entering into each individual cards page

There are so many different options of stuff you can find the value of. I think it’s a great idea to add Fahlo cards.

Many people collect rocks, fossils , and gems.I think it’s a great idea for the app because it increases our enjoyment of the app.
