There's a bit of collection information found in the Quest tab, but not nearly as much as you would probably like.
There is a bit of information missing, such as RoK shinies, rewards, and more listed locations such as zones.
I just haven't had the time to finish the information started, or expand on the information available.
Seems quite the under taking if you ask me, so... my advice is start throwing information together, and find others willing as well
