Didn't see this immediately in the feature section but would like to have a section to track my Totaku collection. Would be willing to help fill it in!

Currently when I try to export my collection the option is only available for gaming and pokemon categories. There is no option for Baseball, or other sports cards info to be exported. 

Not really a feature but an idea for another category. Hallmark Ornaments would be a nice addition to your trackers.

Add a filter so that you can see items in your collection that have recently changed in value.

Currently when you add a Pokémon card through the 'one click' add to collection, it defaults as a PSA 7.

Would it not make more sense to be added as ungraded? . My whole collection is ungraded so when adding cards I either need to 'add with details' which adds at least 4 more clicks and takes me away from the list of cards. It would be a real quality of life improvement.

You should be able to have variations of graded cards other than PSA; such as, CGC, GMA, etc. Not everyone has PSA graded cards and therefore PSA isn’t the only main grading service there is. It’s difficult to find prices for CGC graded cards.
