Re: [APML] Dark Skies?

Hi Mike, Chuck, and List:
Does the darksky map allow you to input your specific position
(longitude/latitude) or do you have to point at the map and click to see
what long/lat the applet thinks you're pointing at? I think I'm getting
pretty close with iterations of pointing/clicking, but it would be nice if
it worked the other way as well. And is there a zoomable version somewhere?
That would be REALLY nice!
