When you tap on the magenta lines while flying they get annotated with heading, and distance.  Is there a way of getting them to show track (desired) instead of heading?  By forcing zero wind if no better way of doing it?

Do you use the DI at the bottom of the screen? That works with track, and can be used in a collapsed state where it only advises if you need to turn slightly in order to be on track to make your next waypoint.
