Does anyone have any tips or tricks for finding duplicates in the minion zoo? I'd prefer not to have an extra copy of anything languishing in there, but I'm also not keen to attempt to go through it page by page.

They seem to be sorted Alphabetically for me. When I have duplicates they are next to each other.

Luna's method seems most usable. Like I can tell you have 2 Caluckos and 2 CD of Ultimate Terror's fairly easily with it. The best I can do to avoid duplicates is Account Search a minion to check if it's already in the Zoo before I decide to add it.
