There's a list for custom companions and a list for custom accessories, what about a list for custom backgrounds? The only way to find any is sifting through the wishlist drop down.

Likewise another thought is being able to sort by monthly release. Like selecting a breed before being allowed to pick a coat color in dog search, it would be very convenient to be able to pick a month/year and have a drop down below it only include the items from that monthly release.

For example, a particular month might have several companions that give the same effect, but some are far more expensive than others in the user's shops because they might be more desirable for the look and you just want the effect as cheap as you can find it. The only ways to find the various companions is searching the list/shops or asking and if they're all different kinds of animals it makes it harder to find them. Another example is it would help with putting together themes for the beauty shows.
