When someone has multiples of the same card
I have a suggestion to possibly add to help when someone has multiples of the same card. If there was a quantity column it would be very helpful in keeping track of my collection. I know I can add copy now but it is difficult to know how many you have because you have to search for them. It would be a great update for keeping track of someone's collection.
This is added now. You can add multiple copies of the same card to your collection by changing the "quantity" value in your collection summary view.
