Since we already have 5 default camera views (hotkeys: '1'...'5'), maybe a custom camera view could be implemented.
This way the player can then switch between the various default camera views and the custom camera view (example hotkey: '0'); which the user could define (example hotkey: <shift>+'0'). And the camera settings could be saved in the Prefs.ini; allowing this preference to be available in other game (saves).
