It can get pretty annoying having to check "Did my pet already read this book? Do I already have that plushie in my collection?"

When hovering over a plushie, beanbag, sticker, or any other collectible item, there could be some text or an icon in the pop-up box telling you whether you have that item in your collection or not. Food, toys, and books would say whether your current active pet has already used that item. It could also tell you whether an item is in your armory and wardrobe.

Heck, if the staff is feeling extra greedy they could make this a gold account-exclusive feature.

Hovers already take a while to popup. Adding an account search to the background takes too long. Also what of multi-use items?

I don’t see this as being feasible without increasing the time the hovers take to load and likely causing a lot of lag.

While it would be a nice feature I just don’t think it’s something we need when account search is super fast and easy to use and had some nice updates done to it recently.

No for the obvious reasons pointed up above + I can see it causing (even more) massive lag
