So, one thing that I really would like to see is being able to have different coloured lights, for example, being able to set torches to emit a specific colour of light, like orange, or green. And, then to have an option to animate that light to make it look like a flickering torch light for example. This would add a lot of atmosphere and coolness to the light sources we can place in game. Could even have flickering animation, pulsating animations, etc, etc.
