ver 2.7.54

I fixed a bug where the mileage text did not change to white when in Satellite view. Two new features:

1) clicking on a elevation point on the elevation chart will cause the map to center on the corresponding marker on the map.

2) if a point on the elevation chart is red and the points to the right have updated, then this point has probably recieved bad data. Also, if an elevation point is at an elevation of 0 and is obviously wrong, this point also recieved bad data. Clicking on the point will requery for the elevation of this point.
