It would be nice to have the system set up like the vaults when looking through the items left to eat. Specifically the option to sort by price.

Support, especially because there are so many food items on the site. I'd also make a lot of use of a similar feature for unread books. Right now, I've wishlisted everything that my pet hasn't eaten/read so I can spot it as I'm questing, and it's a lot to keep track of lol.

No idea how this would effect the servers, but I know I'd really appreciate a feature like this.

It's already possible to form collections on the fansite SubetaLodge, and then sort them. This is a nice idea I suppose.
