I was really hoping that for the money it would be more than just toggling grids on and off and map tags on and off. The only other function is that when you engage player view the secret rooms disappear but it still leaves a big blank spot. I was really hoping that this was something I could use to where I could reveal one room at a time but its just a big old map that shows you everything so you can't really show it to your players without them seeing the entire layout of the area. Very disappointing. Its pretty much just the map folio.
