I would like to be able to decide ahead of time how objects will have lighting applied; Wall, One Way, or Transparent. I think it could be a toggle on the Lighting level. So you toggle it on and all objects from then on are created having this applied. Change the toggle or set it back to default when you are done with that type of object. Here is one way I would use this. When I am populating a room with tables, a bench, or a low shelf etc. I like to apply a Transparent Wall so the objects can be seen over but not walked over. If the objects are such that the PCs would not be able to see over them apply a regular wall... This will speed up map generation. Of course keep the edit-ability so you can tweak objects that were created during the time when you had a toggle turned on.
