This app is really awesome. I love building the layout, its like playing with useful kick-ass legos! I'm trying to set up a controller for my DMX light controller to control LED lights. I bought this app to try and set up some really handy presets, which I could then control with a foot controller to give me lots of flexibility.
To accomplish this I want to send some channels on and some channels off at once (eg turn all red off and all green and all blue on). So it would be really handy to have a supercontrol which can invert subcontrols individually, like a checkbox in the subcontrol list that would invert just the selected ones.
