Have you thought of contacting Jorin about this so the feature could be added to the game? I suggested this as a future feature, but utterly lack the coding knowledge to accomplish it. With a coding example already in existence, they might be more prone to add it.
You've also prompted me with this post. I'm going to venture out on some windswept semi-rainy looking days now for dark skies for our daytimes. Here in Northern Michigan, we get our share of those, and then some!
