In the new dynamic lightning system, if I turn on Night Vision for a token, they see in the darkness as bright light. In the 5E system at least, Darkvision turns dim light to bright light and darkness to dim light. I am sure there are other systems using a similar approach. I would like to be able to set Night vision to count as Low Light instead of Bright. Optionally, I would like a Darkvision setting which simply improves light level by one, not two.
