Is there a way to see all the items in my collections such as trading card, plushies, and beanbags? I swear I've checked over everything trying to find it, I wanna see how many i have in each collection and how it looks. help would be greatly appreciated :)

go to subeta->games, and scroll down the the "collections" section. You should find what you need there. View your collection, see items you have, items you need and a few other options :).

You can also look on your profile under Extra Userinfo. :)
