Allows you to see all your pets in the stable. You will have to call the pet to have it be scanned by the addon though. In the picture the beats with the glow are beasts that have been scanned and you have a 3d preview.
A large database of pets to search through to find just the right one.
There are plenty of filters you can select from, such as the type of the beast as well as the expansion, and looks you either do or do not own.
