Fog of war

Hi. I think Inkarnate is amazing, but I don't understand why you haven't developed Fog of War yet. It's a very basic tool for map editors, and I really need it for my maps. I don't like that the party can see the entire dungeon before they've set foot in the dungeon. Today I place big black squares over my rooms and then delete them as they move through the dungeon, but this is quite time consuming and it's difficult to mark the squares without hitting something beneath them. This is also a mood killer that I have to fiddle with this. So, I would really appreciate this tool :) Besides this, it's awesome!
