A way to make our own component, I get this idea from a game called Turing complete, basically we make a module lets say a BCD converter for example (Binary to Decimal) the practical uses of this in Minecraft are limited but lets just say we want to use this in many of our designs. Normally we would just have to take a picture or remember our design or turn it into a dedicated board and just copy it in creative or something, this feels clumsy though. Instead why not make a new editor where we can make a design and instead of using the digital/analog in and out we use just an in/out pin and then when we are done with the design we can save it as a new custom component to be used in any of our designs. If you aren't sure what I'm talking about, sorry I'm not the best explainer.
