Heading Vector (HDG)

Hi! OruxMaps is a great software full of features, I wish only one new feature, Heading Vector.
I am a Sailor and it would be useful to see where my boat is going to, boats heading. The ship’s heading (HDG) is displayed as a line with an open arrow head from the front of cursor. It should be INFINITE, other words the vector will extend to the edge of the chart window. Then I could see immediately if my boat is going to ground on the rocks or not. This would be a nice and useful new feature! Ari
