See-through/Trasparent color for Draw Shape

I think that can be a good thing if you can add an opacity selector (like the "fog of war" one) into the Draw Shape color selection menu. it can be used for some time-limited visual effect over the map or for a "second level fog of war" in eg. when PC explore a section of a dungeon the black fog of war go off, but when they go ahead the GM could put a trasparent layer to mark zone that they could not see (a sort of Static Illumination System) P.S. sorry for my bad english

I like this idea. In my games we often use Draw shape for area effect spells like Web or Wall of Fire, Or for effects of some spells that change the terrain. Having Transparency can also add more depth for people that like to draw their own maps with the draw tools and they can use transparencies for fog and terrain features. Transparency opens up a lot of options
