The sad Catch-22 to maps is that the more detailed and exciting a map is, the more distracting it tends to be during combat. All those amazing artistic touches on the map image, coupled with the various item tokens added to the Map Layer, make things pretty busy when you suddenly find yourself juggling a party, npcs, spell effect tokens, range rulers, condition counters, and more. It'd be great to be able to have a slider to fade the Map Layer in and out (with a custom color beneath), allowing the GM and players to focus solely on the Token Layer.
