Design of constellations and the name of stars

Downloading a new SVN version of Celestia I noticed that Auriga Constellation was modified as suggested by Vincent in another post to match with charts of constellations published by the IAU.
I think almost all the constellations should be updated.
I have reworked the asterisms.dat file to display all the lines of constellations as in the IAU charts.
I don’t think that in most cases the distinction between thin and thicker line is important. In fact most of the constellations are drawn with thin lines. If we ignore them, there will be almost nothing to draw!
If a bold stroke is actually necessary (and I don’t think it is), I discovered a workaround. Just draw the line two times as in the example below.
And the result in Celestia:
In case you find it useful, I join the file with all constellations updated.
Only UMa has bold lines.
And lastly a request.
In the case of binary stars, is it possible that the name displayed beside the star be the proper name of the star? Especially when looking at the constellations it is nice to see Capella or Menkalinan rather than Alpha or Beta Aur. If you want to learn the constellations and their stars and after that go to contemplate and recognize them in the night (I know that scientists don’t worry), Celestia must display that name.
