The ability to import and image with transparency to use as a mask/ object in the dynamic lighting layer. It would be highly useful when creating a map, if you could make a solid image of the negative space around a map that could be imported to the dynamic light layer and be recognized as an object. This would speed up the creation of dynamic maps to no end and make it much easier to keep your players on a map (particularly a large one) I noticed this was suggested over a year ago but didn't get many votes so I am suggesting it once more. I'm new to roll 20 but and at the moment this would be the tool i would find most useful.
