There are THOUSANDS of different pets and items in the archives and as the numbers continue to grow it gets harder and harder to find things. Here are my suggestions to streamline things
1.) Ability to filter by rarity and also by “owned” and “not owned”
2.) Ability to use multiple filters at once - for example you can filter “uncommon horses by Lilian Nightshade”
3.) For items you can filter by species, owned/not owned, body area, and type (basically filter them the way you can in your inventory)
4.) Multiple wishlists - this way people can separate hoards, dreamies, pound, etc.
5.) Remove recently acquired items from wishlist. Similar to the way you remove pets
