I'll try it out when you are happy with the beta. I will say this, when I used the old controller GUI and programmed those buttons, many buttons on the C4 no longer worked properly. Through an update (app controls built into the new Shield - not the Shield itself) over the last week, some of those buttons have begun working again. But it's still very slow. So, it may be an app that allows the remote control to work that's the problem, but programming is not my background.
