Seems to me that, at least for people with Playstation/xbox style pc gamepads or those with good joyticks, that either the right stick or POV/hatswitch would be the best way to control the freelook option should you implement it. Although you would ovbiously need a different solution for keyboard/mouse users. There, a shortcut makes sense I guess to automatically center the view on various panels, though an actual *free* control could be mapped to the numpad or something Or for mouse users, forgo the rolling control and have holding down the right mouse button (or both buttons, or center button - who doesnt have a mouse wheel these days?) and move in direction you want to look. Actually I quite like that Idea for mouse control as when using the mouse I almost always use the keyboard for throttle, fire missiles, anyway.
