Distance from current position to selected point on track
Menion, I just realised that the most frequent question, if following a route and out in the wilds, is not answered by Locus directly:
"Wait. What's the (on track) distance from here until... the next hut?"
This simple question comes up so often... Somebody asks you "how far until...?" The answer could be presented in the trackpoint popup or in the new point info.
Currently I do the maths with values which are presented. E. g. (targets distance from start) minus (currentpos distance from start).
