I would really like (if possible of course) to see the skinning percentage as it appears from the loot.
It would also be awesome to change the color of the monster outline to red when completing the Common, Rare and Legendary Bestiary.
Just an example, but I want to say something that indicates it is "done"
(Not necessarily changing the color of the box)
