How about just flying? I find it hilarious to see a lone plane, climbing through 30,000 feet on an un-altering straightline course across 4 sectors on its way off the map because someone put their plane on auto-climb and walked away from their computer.
If you log in to fly, then fly. I understand going afk for a few minutes at a time, but there is no need for a new dot command to auto-level at a certain altitude. You might as well ask for combat autopilot so the plane fights for you too.
