enhance planet trials

Alexander

trail Lines:
SolarSystem.setFlagTrails(true);

I would like to see:

Set Trail colors independently for objects: i.e. sun and moon

Set Trail linewidth independently for objects: i.e. sun and moon

but more importantly:

Allow to make the lines track the connection between objects: i.e. the Sun and Moon

Allow for long time periods on the line fading to make it easier to do calculation beyond 1 year

purpose: topocentric Archaeoastronomy

Thank you very much

Steve
