Current weather icon: Request to include night time icon (moon) in the set

The current weather icon set currently does not include a night time icon, which is typically a moon. Can this be added to the set? At present, a sunshine icon appears to show clear weather, day or night.

I agree.
I like this feature on my weather app (phone)

for day and night you can use a formula to show these icons according to opacity, and you can even make a circle that rotates showing day and night.
I think it would be good to add this function in an icon that summarizes the 4 images with the 4 formulas necessary to achieve this effect, as well as the weather icon
