2015 or 16, there was an app that did it, Dashboard or something like that. I don't have it anymore after several computer crashes and house fire. But maybe someone else can remember that far back.
Dashware, was the name
I talked to the seller of my RC Plus about such a thing, if for some reason the RC Pro firmware had to be reflashed. I was reminded that the cost of shipping, plus import duties both ways might discourage that idea. I don't know about the person...
So, I've had this RC Plus for better than a month now. People getting upset about non-working buttons don't understand. They don't correspond to buttons available to the RC Pro controller anyways. So, I didn't lose anything as far as use goes...
