This is a minor addition that I think more people than I would find handy.
When I travel longer distances by flying mount I try to align the player arrow with my destination and activate autorun. This is less reliable than it could be, though, so what I'm suggesting is a module that perhaps makes the player arrow fire a straight line to the edge of the map, making it easier to setup that beeline.
Can you use a waypoint to accomplish the same thing? Set a waypoint at your destination and you'll get an arrow on your screen pointing in the direction you need to go. Facing in that direction and then activating autorun should do it. This has the added benefit that you don't need the map open to see if you're still on track.
