This was suggested in a different way by AEIOU titled Reveal for GM. I like his idea when you reveal partial information or only to some of the PCs. As a step before that I would like to suggest a check box for GM Direction. I'm running Broken Moon in the Carrion Crown Adventure Path. There is a lot going on during the investigation part and it's not linear. It would be nice to be able to check off GM information that I've already dealt with.
