Displaying speed and coordinates with multiple tracks

[McPringle]

Since v1.4, GPX Animator displays the speed and the coordinates of the track in the animation. What happens when the user selects multiple overlapping (!) tracks? What is the actual result and what should be the expected result?

To make things easy, maybe displaying speed and coordinates should be disabled when multiple tracks are added. Or is it possible, to easily identify overlapping tracks and disable the display only, when we have overlapping tracks?

Brainstorming time!
