The existing feature that enables setting the time to Dusk or Dawn is useful. I wondered if it might be possible to add evening and morning civil and nautical twilight (sun altitude -6 and -12 degrees) to the presets. Not a real high-priority request, I know, but something that doesn't seem all that difficult to add.
By the way, when I set it to Dusk and Dawn, the sun's altitude is always something like -17 degrees. Is there a reason you are not using the commonly accepted value of -18 degrees? Thanks.
