 Dan, we discussed this briefly last August.

 At one time, the map showed all of the GPS position reports received as a
 station moved, so more and more dots would collect.  I think it was
 considered a bug, and fixed so only the most recent report shows,  as it
 should be.

 Well, it was definitely a bug because there was code to prevent it that
 was not working :)

 If it isn't too difficult, could it be an option?  It's nice to be able to
 see where communications worked and didn't work, and the line of dots can
 help find that sweet spot.  If it's difficult, or might cause some other
 undesirable problem, then I wouldn't consider it.

 Yeah, it's probably a good idea.  It's a bit of a "can of worms" because
 along with the ability to keep the history, you generally also want to be
 able to delete, summarize, save, etc that history.

 How about for the time being, I add a flag that lets you say "keep
 history" or some such.  This would stamp the time (or something) on
 incoming reports so that "KK7DS" would become "KK7DS.08190906".  When the
 next report from that station arrived, it would be similarly stamped, but
 since it's a different name at that point, the existing code would
 consider it different and not replace the old report.  This would then let
 you use the existing delete-a-point function to delete a received point in
 time.

 It's a bit of a hack, but it's something I could do in an afternoon.
 Would that be worth it?

 I just thought of something else:
 I could also continue to update the KK7DS point with the current position,
 but then create a duplicate point of KK7DS.08190911 and put it in a KK7DS
 group.  That would let you see the current position, as well as where
 KK7DS has been.  You can toggle the KK7DS group on and off to show or hide
 history for that station and delete the whole group to erase all history.
 I could also make the group not persist on restart so that you don't end
 up with years and years of history for every station...
