I noticed that most planes have an invisible barrier that prohibits the camera from freely moving about. For example, it's easy to move the camera in the Daher TBM cabin, but the same can't be said for the Cessna Caravan or Beechcraft King Air or Cessna Citation. Since the cabins are already fully rendered (with the exception of the airliners and the Citation Longitude), it would be nice to have that limitation removed.
