Hi,
The GPX specification allows for a <cmt> field within a <trk> - which is already accessible in Topofusion by right clicking on a track and choosing Edit Track Information. Would it be difficult to have Topofusion put the total track length there (e.g. "4.1 miles") instead of leaving it blank by default? I've been adding it by hand when I use the gpx files elsewhere (e.g. overlaying them on googlemaps) and it's very handy not to have to recalculate the track length.
Still love the program and recommend it to people. As always, thanks!
