JOHN DOWSON - FSUIPC7 FOR MSFS
Excellent piece of software. I have not used the graphical interface but "only" the LUA scripts. It took me some time to get comfortable with scripting, but wow, it is powerful. I could not live without this little tool. I use it a lot in conjunction with my Virpil control panels where I not only use commands but also read states of various things in the sim and assign lights to all the LED's for buttons and displays.
