ok, I think I see the problem now:
(+ man page updated)


steps:
- Start GpsDrive
- [Find]
- max distance 0.25 km from current position [Find]
   (6 POI found & listed in "Results" list)
- click on diff't wpts in Results list, cross-hair target and connecting
   line jumps to selected POI as I click on the entry in the list
- I can't select multiple POI from the Results list with shift-click or
    ctrl-click.
- With a POI selected in the Results list click [Edit Route]
    New window opens for Edit Route
- "Route List" is empty

ok, progress:

-> at this point (re)clicking on the currently selected POI in the
    Results list does nothing! I need to select another POI from the
    Results list and then back to the first one selected before the Edit
    Route window was opened and continue from there. :(



also, it would be nice if the Route List window gave you bearing* between
each route-point in the Route List. Currently you get "#, blank, Name,
Distance, and Trip (cumulative distance). (e.g. my handheld garmin gives
you that angle in its current route list of waypoints.

gpsmisc.c currently calculates that angle in calc_wpdist() but doesn't
give access to it. I'll submit a little wrapper fn in SVN later today
so we can have access to that.



terminology I use (today):
 bearing: angle from you to the cross-hairs/next target(wpt)
    (compass angle of shortest line between A and B)

 heading: direction you are currently facing

 course-over-ground (COG): direction you are currently facing
    "COG" is used in sailboat racing calculations, where I know it from


I started a "Terminology" wiki page to try an centralize these discussions as they seem to get lost in the mailing list archives and repeated.

edit away!
