Coogan's thinking of a -1 for this idea makes sense only if you completely disagree with the ability to look at the map.
At present.....to look at the map.....you have to divert your eyes from the entire game.
I would use a key command that would throw it on your lap...showing your position to maybe 1/2 or 1 sector out, and reduce your little airplane to a crosshatch with arrows. The one thing that bothers me is when using the map itself is that your icon, even in max zoom, covers up spawn points, town locations...etc.
I don't think that you'd need a zoom function or be able to scroll through your map on your lap, you'd still have to go to the clipboard for that
