I find that if I add new layers to an existing drawing:
1. They are always visible
2. They show up in all the scenes I have created.
Is there some setting I am missing that would allow me to add layers and not affect scenes already setup?
My solution has been to make a drawing template with enough layers to start so I won't have to add layers during the drawing process. This seems like a sledge hammer solution since I had to draw on each layer to make it work.
