@ Sonarman - I'll send you a copy of v2.1.0 as it stand now with this feature if you do a tutorial on what this is used for and how to use it. Sound fair?

Yes, that sounds fine, most of the guys here will know what it's for but for newbs it might be nice to have a quick tutorial.(although at your current speed it will be out of date in ten minutes time!)

Pressing the keys used for the heading bar results in 0.5 degree changes. If you press shift with the keys you get 5 degree changes.

Maybe 1 degree increments would be better than .5 as you never need that much accuracy.

Now should I make the two draggable compasses slaved to each other? If you drag one the other follows? Then when you click on the draggable compass it switches to the other one?

Probably best, if they are slaved and appear to the eye to be one compass.
