You should know how there is no way around it, however you put words, there is way to see how want is achieved, no becomes yes of something else etc. It is just passion I guess Is there changes how importInputs behaves? Will it be possible to pass gear to slave unit from master? That is for example coupling two locomotives together or buses. I doubt that official content will have need for that though, so might be that it is needed to craft with custom code, if that is possible? Still need to study lot more of this to understand it all better though.
