If you get the time or the inclination, could you add line drawings of the constellations? It would be very nice to toggle (off/simple/elegant) line drawings of the Crab, the Archer, the Scales, etc. laid over the constellations as viewed from the solar system/earth. It would also help my girls to visualize the shapes that lead to the choosing of the constellations. Okay okay.. I'd like to see that, too. But it's for them.. really.
Thanks in advance for looking at this, and Kudos on an incredible program.
