Hi Umberto,
thanks for replying.
I read your statements about this issue a few times before, but I am not happy with it until now.
I spoke to a developer last days and for sure, until today there is no, via network reachable API (interface), mentioning without a module in P3D itself, to be used by third-party developers like e.g. FSFlightControl.
It would be a great success in future for your software and thus for all users, having the opportunity, not scolling through menus anymore and giving up some reality in flying ... letting e.g. FSFlightControl inside and on top their software-surface and even simpler, me as a user defining some keyboard-shortcuts, having them on buttons and selecting GSX with it ... a wonderful thinking ... I am sure, you will be pleased what people say, buying your great software in the future.
