This is an aaddon that remembers stuff about the creatures you come across in the world, and then stores it away for future use. Sadly I havent't written much in the way of "using" components yet, so it's not really a very interesting mod unless you're either curious, or hopeful that I'll get around to it.
It does have a command to tell you the names and level ranges of everything you've seen in a zone.
It SHOULD have a command to let you search by name, but doesn't yet. If people start using it i'll be more inclined to add it 8-)
