Sneaky spacelegs, like it Elite: First Encounters had three cameras, front view, rear view and external free, so yea... #freethecam (probably won't happen, took 'em three years to give us the current setup).
Only issue I can foresee is that the free camera can clip through objects. Supposedly, internals of some ships are already mapped out. I'm not sure how a cockpit free camera would deal with that, assuming FDev hasn't finalized/rendered those yet.
