For Solar observing it would be really useful to have observing conditions extend to daytime.
Currently only nighttime is covered.
Also an important factor for successful observing during nighttime is the phase and presence of the moon.
Having an indicator showing the impact of the moon on sky darkness (on an hourly basis) would help a lot for planning in general an spontaneous sessions in particular.
A simple colored square like on meteoblue could be enough for most.
