Altitude graph of a loaded track

[matt]

Hi,
i like the existing option to display the current position in the altitude graph, below the map, while following a track.

What would be also nice to have:
A track is just loaded on the map, and it's altitude graph is shown below the map. Now someone could
- either move a dot/marker along the track, while a dot/marker simultanously moves along the altitude graph
- or you move the dot/marker in the altitude graph, and the dot/marker in the map moves accordingly.
