Nope. You can change plane, loadout, and fuel amount in the tower and then take off on the runway you want faster than going doing everything by moving from tower to hangar and by clicks in the hangar.
.plane 41
.fuel 1
.loadout 0 0
.fly 1
The metric here is what the fastest way is. So if .e6b was faster than pressing esc, it'd be worth modeling. Come to think of it, you do lose the e6b when you bring up some (not all) of the other pages.. either .sr or war status (for eny values) or strat reports, or CV waypoint command. So it's not totally invalid a request. But you shouldn't hold your breath for it.
