Bertrand, the idea of being able to set label colors seems
reasonable to me. I've just modified Guide to allow this. (The
.TDF files for these datasets will _also_ need to be modified,
to set a default color. Shouldn't be a big deal, though.)

I am indeed thinking that the ability to change symbols and
fonts would be helpful. The former can already be done by
editing the .TDF file; details on this are given in the user
manual and at http://www.projectpluto.com/tdf_info.htm . That
said, most people would probably be happier with a "Symbol"
button which, when clicked on, would bring up a palette of
available symbols. Select a symbol, and Guide would then use
it for that class of object. This, and changeable fonts, are
on the "future" list:

John, I've revised Guide so that it'll show the MPCORB
data for the asteroids you've added. (Keeping in mind that,
in general, you should just use MPCORB. That replaces and
updates _all_ asteroids. At that point, adding "new"
asteroids with the "Extras... Add MPC Comets/Asteroids",
doesn't accomplish much. The only real benefit would be the
one you mentioned: in the "List Current Asteroids" function:
the "new" asteroids will appear at the top of the table.)
