Not much really but some new things would be nice like having the ability to disable the HUD while using the free-cam as it can get in the way sometimes. A few more cinematic camera angles and that's about it really :)
There's currently a few bugs that get in the way. These being as you fly next to the aircraft with the camera and the camera goes "out of range" you could say and when you use the replay feature while using free-cam the plane seems to be having a mind of its own, jumping around everywhere haha!
Also a few more cockpit cameras/angles would be nice :)
