I am in the process of organizing my card collections while also continuing to add to it. This has created numerous instances of identical listings in my collection for the same card. Let’s say for instance I scan in 5 bulbasaur cards. I scan one of them, set the quantity to 5, and add it to the collection. Later after opening a pack, I get a new, identical bulbasaur. Once I scan it in and add it to the collection, I’ll have 2 listings for that bulbasaur. One listing would show a quantity of 5, and the 2nd listing would show a quantity of 1. Since i use the default setting for condition and i verify the set before adding the cards to my collection, they are identical listings that are separated due to the time they were added. 

I would like a feature that allows cards with the same values (i.e. condition, set, etc) in my collection to be automatically condensed. I would rather see a single listing for a card with the correct quantity rather than a bunch of individual listings from each time I’ve added that same card to my collection.

I would like to see the popularity of different items in a set (for example, how many other collections an item is present in) and to be able to sort items by popularity.

I see we now have the option to add Ebay sales. Would it be possible to add Heritage Auction sales as well? There are a few items that weren't added until after the sales happened, and they're rare enough that no sales have been registered since. 

Add Star Trek Cards to the site

Add how much value is a card for the condition of a card. On ebay it says what condition a card is before you buy it so i should say whats the price of a card for a specific condition for example NM or MP

Could we add card condition for accurate prices on damaged, Light played, heavy plate,d and mint cards?

They are some quality cards and have great artwork. 

FAB is getting popular would be nice to be able check off collections

Allow us to track prices of Pachinko machines in our collections. They are arcade adjacent in my opinion and fit right into a game collection. (I realize this is a relatively niche request)
