I'd like a new camera like god-mode only it's a free camera. It's not tethered to any vehicle or aircraft, and can be placed (via key presses??) where you want it, then rotated, tilted, and so forth, so that you could set the camera up for fly-bys, or if 2 planes are in a rolling scissors, set the camera stationary off to the side and watch them roll around each other from a slight distance, or fill-in-the-blank.
Basically just free it to look wherever you want, but reset it to chase on the player's plane by default (so you can go to free mode, screw around, go to internal, then back to free, and it's reset to a default position similar to chase -- this way you can move the camera long distances then reset without having to move it all the way back).
This would help with films, with screenshots, with a lot of fun things associated with this game.
