The keyboard controls don't appear to be editable. That can make some controls inaccessible (for example, a laptop user who has to use Fn+Down to get PgDn might want to remap PZB Acknowledge to be something more reachable, given the short amount of time you get to press it before the brakes go on…) It would be good to have an in-game editor to allow the keyboard controls to be remapped. It would be ideal if it could also remap external controllers, rather than having to use third-party software.
