It already exists… as a bug.
I don’t know if the bug happens with anything else than a X1 gamepad though.
If you move the mouse and then your head, you’ll see a dot following the center of your head, and you can aim at buttons this way and press A to lock on them.
It works well actually, but unfortunately, because this is a bug, the dot disappears after a few seconds. You can still aim but don’t have a dot anymore which is not really convenient.
There is things to “fix” this:
Learn where the center is. This is pretty much what I’ve done and I’m getting pretty good at it.
Move your view around the cockpit until a button glows blue, lock it (A) then release it (B), the dot will be back, again for a few seconds.
Move the mouse and then your head, once again, the dot will appear for a few seconds.
If you have the VFR map open, you can even zoom in/out with the left/right trigger, and move around by pressing A and moving your head.
I wish there was a simple toggle dot on/off and we’ll be almost golden (there is still no interactions possible with cockpit touch screens for example, or I haven’t found out how to yet).
Hmmm, I have a white dot, that moves with the headset. depending on the control setting it highlights the controls on hover blue and You can change values or push buttons.
