Tyler Crowley appears in every book except Breaking Dawn and is so categorized. Bella Swan's truck appears in the same (I think), with a mention of it dying in BD. But it is not categorized as such - there's not even a section indicating where it appears.
I definitely agree that appearances need to be more uniformed. I believe you criticized me though when I used Appearances for something other that the literal appearance of a person, instead opting to use it for an inanimate object.
