In your gpxtrackmap.php there is a part (line 1013 - 1026) where you mention the use of the track from Garmin files. It's commented out (see below) for use in version 1.2.5, which isn't availablble (yet).
//V1.2.5 auto track color from Garmin files
// <extensions>
// <gpxx:TrackExtension>
// <gpxx:DisplayColor>DarkGray</gpxx:DisplayColor>
// </gpxx:TrackExtension>
// </extensions>
//
// if ($this->_params['trackcolor']=='auto') {
// foreach ($trk->extensions as $trkexts) {
// foreach ($trkexts->gpxx:TrackExtension as $trkext) {
//echo($trkext);
// }
// }
// }
I would appreciate this option very much, so yo can add two tracks in one file with different colors. For example to add an abbreviation of a track if you don't want to walk 19 km but just 14 km.
I tried to remove the // in this part (or only the php-part, not the extensions part) but than the plugin doesn't work anymore.
Should I do something more or is it just not ready yet?
