I searched for suggestions about Turret View and cruisers/destroyers/battleships (the larger ships). The original, unmodified game only had fighters and freighters.
The "camera" setting enabled in "H" so that you can fire in any direction needs to be addressed. I suggest that an option be placed in the launcher to change the distance of the View Camera from the Center of Rotation around the Ship, so that the player can see the ship and surrounding area at the same time, especially when flying a Destroyer and taking on multiple NPCs. The solution may shrink opposing ship size, but it is preferable to being blind and relying on the targeting system for aiming.
An alternative would be to make it so the larger ships are transparent in turret view; the Rheinland is almost transparent now. I have no idea if the engine can support this approach. They did that sort of business in multiplayer Colin Mcrae 2005.
I believe that the launcher or other programming fixes the alignment of the GUI for widescreen, so adjusting the camera upon start or install should be an easy task.
