It would be nice to be able to view your collection in a grid of image thumbnails. Example image from Notion of how I mean. It makes it easier to see the cards visually rather than a massive list for those of us who are visual searchers / enjoy looking at the actual cards.

Some how fell in to this new collection of Anime TCG. Weiss Schwarz has a plethora of sets of anime TCG that are cross playable and have a fallowing. TCG and Ebay have price points that can be tracked for collectors. There will be a small challenge in adding the various sets but would love to see if these sets can be added for tracking and price points for all users and collectors.
Allow imports by PSA certification number to allow easy mass import of collection. Use PSA API to look up the Card and Grade and add to collection automatically without having to add extra description of the card
I am kind of amateur at collecting and I know that other people are also so I believe that it is important to add a coin scanning feature to make everyone’s life easier. It is really hard for me to specifically search for coins and I think you should add that feature in the app.
Can we get data from https://tcgrepublic.com/ for the support of pricing on Japanese cards such as the Yu-Gi-Oh prismatic art collection from Japan.
At the moment we only have eBay data but we could do with more accurate data from TCGReplublic
Add ability to sort a collection by the cost so I can see the items I paid the most for.
Hi! Specifically on the iOS app, would love a way to lock in a set before scanning. Particularly useful for yugioh where a card can be in a multitude of sets... often, lol.
Add conditions like NM, LP, MP, HP, and DMG besides just "ungraded". I'd like to be able to easily sort based on the condition of my ungraded cards and it's a feature other apps and services have
Much like you can for adding items to your collection, for me, that's pokémon, I wish I was able to add the same details for an Item that i want to get in the future
When adding to my collection i can choose the grader, the graded condition and how many i have.
I want to be able to do the same for adding to my wishlist.
