Thanks for the reply, glad to hear that it's planned!
I have many layers in my game (150+) , and layers I need to load from another room have varrying depths, I don't wanna set the depth of the layers in external rooms as it will make it hard to make changes. IE if I add a new layer into my main room, now depth changes for all layers and I need to change it in all rooms etc. I also have code that operates on the layer names directly.
