Please add fog of war

We need this asap, me and my friends don't use this amazing tool due to the lack of fog.

The ability to drag and drop any map and have fog of war work would make the a SUPER useful tool.

This lack of a feature makes roll20 better for online play as you can keep things hidden.

No hate here, just want to see this product excel and this feature would hands down make this a S++++ product.

Hope this is around the corner :)
