It would be cool to have walls/lines on the GM layer able to block player movement. This is similar to the recently implemented dynamic lighting walls that block movement, but you can see through these "walls" - this would allow uses in situations such as: D&D Wall of Force spell, strong winds, warding circles, invisible mazes, etc. Alternatively, as I have seen suggested elsewhere, it would be cool to have variable opacity dynamic lighting walls that block player movement... but the gm layer walls might be easier to implement.
