i would also like double side shading.
so that i could make one side of the plane  green and the other side red. one side specular and the other side not. what are the chances?

plus it would be nice that we could in light settings choose an object or figure. so for example light 1  only works for the ball and light 2 only for the cube. this would be very good so that we could use raytraced shadows for the body  and DM shadows for the hair.
