I'm currently working on an idea with docking nodes that transfer wheeled carts between separated "crafts". One of the carts contains the probe core and power so that as the cart moves between segments actions can be transferred between sections allowing repeated use of the action groups. Given a beefy enough machine and a large enough SPH, this could be expanded to many, many, many digits. The downside is that KSP has no predictable way it chooses which chunk you remain in control of after an undocking event so you have to play with switching between craft sometimes. I've got a good system for transferring state for two sets of numbers, 1 to 9, now I just need to work out how the operations will actually work. Eventually I'd like to figure out a good way to provide thrust to the carts so that they can push levers and such. For addition, I may just start with lights on the cart that light up selective panels as they move between stations but I really think forcing the user to count in a method other than the input (a single button representing a single number) is cheating. My ultimate goal is a single indicator per digit.
