In the flight plan altitude planning window it would be helpful to show the magnetic heading when you click on any portion of the leg you want to adjust. It shows the cumulative distance and the current altitude, would be helpful to see the heading, especially when plotting a course that is very close to a north/south heading. I've plotted a couple of courses that jog around airspace or terrain that end up changing which hemisphere I'm in and I have to drop out to the flight plan screen to see the mag heading and then try to find the correct leg in the altitude planning window.
