Hello! I'm having issues knowing where the CWs are after I mistakenly stored them in my store.

Which made me think that it would be a good idea to have a rarity filter on the search tabs of user shops.

Hopefully my suggestion is a valid one :)

I don't think rarity would be the right thing to use to sort it, perhaps just under either the item type or item use have an option of "Custom Wearable" which you can search for that way. I think the rarity filter may be a bit much to implement.

That would work too :)

If you're having trouble locating where items are on your account, the Account Search page is an excellent resource. I use it all the time when I accidentally put something in the wrong place.
