I would love this, regardless of how important it is. But it'd have to be done right. I would like art for the enemies pages, and I think it'd be cool to have information you unlock about the mob family through battle or "scan", like weaknesses, strengths, etc.

I don't care for it to list EVERY mob in the game, just the families and the NMs, and perhaps important characters to the story, good and bad NPCs.
