To go along with the recently added seat X and Y looking direction, it would be amazing to have a boolean on the composite output of the seat (eg. channel 30, as 31 and 32 are already taken) which can be used to determine if the player is in third or first person view. (For example, it is on when player is in 3rd person, off when player is in 1st person view.)

This would be necessary to make a mouse-look flight model work well in both first and third person perspectives.
