I don't know if this was posted already, but here we go:
Type of improvement:
Gameplay /Handling
Explanation of proposals:
Gunners at all and the Ju87 rear gunner especially are too difficult to handle.
The vertical mouse axis is inverted and can't be changed.
The "lens-mount" moves definitely too slow, compare with the same mount shown in this video:
As a improvement i'd recommend to use a qualifier key with the mouse-movement to steer the mount (lafette).
Benefits:
Added realism through easier, more realistic handling
