I love the idea and want to love the extension! I'm sad, though; I think with the lack of updates, it doesn't seem to understand which dragons I've already completed entries for, and the lack of ability to customize the extension is unfortunate. :(

I recently got back into Dragcave after a couple years of not playing at all, and even longer of only playing during the holiday events. This really helps me quickly identify eggs, and the collection feature is also really useful.
