I think it'd be handy if in your book, pets tab there was a button where you could sort your pets by body type. Open your book, hit the button and the first pets showing will be your "Pet A's", then "Pet B's" etc. That way when working on a project, and want a specific body, you could compare stats, talents, etc. on the pets so much easier to pick the one that you want to use for hatching. You wouldn't have to find one, then go twelve more pets to find another, then another six to find the next.
