Currently, we have four layers, counting the GM layer and Dynamic Lighting layer, neither of which are seen by players. What I would like is a third layer, that appears above the tokens and, more importantly, above the dynamic lighting. This would be nice for things like trees - Make a dynamic lighting blocker in the shape of the trunk, but the top of the tree isn't lit by the light - Or not on the same level. While I would LOVE a multi-layered map designer with each level having its own map, token, and dynamic lighting layer, that's a ton of work for only a little gain. I think just having a layer above the dynamic lighting - and above tokens/objects - could offer some neat opportunities for things.
