I would like to suggest a faster way to search through the collections. I have a lot and it is a huge hassle to look through pages of my collections to see if I already have it. It doesn't always work to buy it, click on it in inventory, to add it to my collections - often it tells me that I already own it. I love collecting these but this is slowing me down.

if you just wanna see if you have a certain specific item, then Account Search (under Personal) already exists. It can't see the Minion Zoo right now, but it can see all the other collections and things equipped/data attached to your pets.

If you want to manage your collection, the fansite Subetalodge already has a system in place for that.

As Has already mentioned, Subetalodge is an excellent site to use for just that (and many other lists for Subeta items). ^_^
