To go hand in hand with this wish ...
I would like see the waypoint course (when viewed on the clipboard) changed from red to black. Then, when setting a course way-point, have the green waypoint turn to red if that way-point crosses into an area that the ship can't sail ... instead of setting way-points and hitting OK and then getting the message that the way-point(s) are to close.
Sometimes, depending upon the chosen course, you can't tell which one of the way-points is bad ... frustrating at times.
