Good idea. It's a bit of a pain to move your head and hit the "TIR Re-center" key.
I believe what he means is, without TIR, you can move your head position in the x, y, and z axis to where you want it, and hit F10 to improve the front view's location in the cockpit. As an example, you might move your head up so you're looking through the top of the gunsight when you're looking forward, to get as much view below the pipper for pulling lead on a maneuvering enemy. With TIR on, the default position is the only place in the cockpit the TIR will 'center' to, so in this example, you have to scrunch your neck down, center TIR, then move your head up. If your tracking is set fairly sensitive, it's less than ideal because your head is now out of 'center' when you're sitting neutral, and it doesn't move the same as being centered.
I'd love to see this as well.
