I would imagine a button in the "flight direction" menu (maybe click in the middle) that fixes a ships orientation in flight so it can move sideways or reverse without turning. Same behaviour like over short distances.
(Similar but not quite the same as the old "allow diagonal flight" which was an odd compromise).
This could be also cool and maybe improve formation flight.
I made this Ship:
Spiral Disk
It would benefit from flying into any direction without turning at all.
Over short distances it already does this.
