Every time I take cover by laying down behind a rock while under fire, I find myself leaning in my chair to look around the obstruction with my TrackIR :-s
It would be very helpful (and realistic) to be able to lean slightly and engage targets from behind cover while in the prone position :-)
I know that there are other positions for shooting around objects while in the prone position, but I just want to simply lean progressively in my chair with TrackIR just like the kneeling and upright positions.
Hope this makes sense.
