I don't know if this would be better suited for the pet forum, but I would love to be able to see my pet's parents and even further back. I don' know how difficult that would be, or if it's even been mentioned before, but my print screen button does not work most of the time. So I go to snap a picture of the parent and come to find out it didn't take.
Also, if I hatch with someone who has an adult but then it levels up to Ancient or Epic, I'd love the opportunity to see what they manifested.
