Cartographers hover an empty tile and click the gray "+" to set it up, or use the "Quick Create" button. A tile can have a Label (up to 20 characters), a Status (explored, discovered, unexplored), a Color, a linked Place, Notes, and up to three icons; GMs can mark a tile Secret. To uncover large areas quickly, right-click a tile for a small menu that sets its status straight to Explored, Discovered, or Unexplored. Note that a tile's status still shows to players even when it's secret — they just can't see anything else on it.
