Hi, I am relatively new to the whole topic of data refs and, in all honesty, I don't fully understand how they work in X-plane. I am setting up a home cockpit for the CRJ 200 with GoFlight modules and got almost everything to work with Sandy Barbour's fantastic GoFlight plugin, but I am missing the CRJ-specific functions. Can any kind person here tell me what the steps are to extend the list of standard X-plane functions, so that the the CRJ-specific functions (e.g. windshield wiper, overhead panel brightness, etc.) show up in Sandy's plugin? I am sure it's relatively easy, I just can't figure it out. Any help with this would be greatly appreciated. Best, Andreas
