so, on the white "paper" space you would have a list (slots) for entering text "kitchen light", "kitchen outlet", "garage door", "clothes washer", "clothes dryer" etc and add some parameters like voltage, amperage, single, dual, etc?
"clothes dryer", 240V, 30A, SINGLE -> voltage logic would span a 240V across both busses?
"air conditioner", 240V, 50A, DUAL -> would have two 240V splitting 25A across each for the air handler and compressor?
"kitchen lights", 120V, 20A, DUAL -> split two 10A circuits on single breaker (dual switches) for overhead and under counter lights to save breaker slots
etc




of course the only new plugins - the sketchucation, open cut, and su diffusion...
