The Free Camera button (RShift by default) is nice, but the only problem with it for me is that you have to hold it down the whole time you're trying to use that view. I would like to be able to zoom in/out or maybe reach over and use my ship movement keys while using the Freecam, but that's really difficult when you're holding down a button on the other side of the keyboard. I've yet to figure out how to hold down RShift, LShift and scroll my mouse wheel at the same time. I think it would be much more useful if it was a latched (toggle) button instead. Just my opinion.
