fishy - if you are looking for the difference between "Course over ground" and "bearing to waypoint" then install the derived data plugin for signalK and look for "Steer Error".  'navigation.courseGreatCircle.nextPoint.steerError' will give you this as a plus or minus depending on the direction and 'navigation.courseGreatCircle.nextPoint.leftSteerError' and 'navigation.courseGreatCircle.nextPoint.rightSteerError' will give you the two steer directions to make an easy race screen with steer left and steer right.  I display them as numbers, not sure about the display types you want

Thanks, that is useful.
What I was (am) looking for is a nice way to show the magnetic compass, to assist in steering, but also 'cause its nice. Still can't find one, but I'll check out your suggestion for sure.
