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. 

I have playboys from 1959 to 1962. Would like these added so I can add to my collection on the app. Also I have had great sucess selling just the older centerfolds. College boys and bars love to frame them and hang. I know pricing may be a problem. But, being able to track would be a assett.

Video games return eBay and amazon ids, but cards do not return the tcgplayer id. I need this id for my application. Can you include this in the csv export or api? 

Add ability to show only specific consoles. For example: only show xbox 360 games.
