Having the default pilot forward view with the ability to save 2 adjustments for it would help. Have them on a button toggle. Set one for fighter mode and one for attack mode.
By accident I discovered the A20 has a more natural glide bomb aimpoint if the gunsight is down on top of the instrument deck. But bringing it back up to the default is necessary for air to air shooting. The B-25H is more natural for a 1000ft alt glide bomb run if the gunsight center is all the way at the top of the reflector plate while using a 5.5k aimpoint marker for the 75mm as the bomb marker release point for 400-600 away from the target.
Then with the FW190 F8 and Typhoon, rocket aiming is more accurate if the gunsight is raised up to elevate the rocket markers. But, I prefer to use those gunsights for air to air gunnery back at the default position.
I, placed a wish for this in the Wishlist forum already.
