We have been in discussion with SI about integrating GSX for a long while. I provided them with all information about what they might possibly use from GSX, it seemed they started doing something, this was months ago, then they stopped communicating, no idea why, then I saw a puzzling message saying they don't want to remote control GSX for some reason, assuming that other developers doing that like Fenix, Leonardo, FS Labs, all did without our consent, when in fact they did it with our help, and we are actually encouraging 3rd parties to integrate GSX and even control it remotely, because it has been designed to be remote controlled.
So, to prevent any further misunderstanding, we added an SDK folder in today's update, where Remote Control is officially documented with a C++ sample.
