Related to this topic i got a vision of future Technological mods utilizing a new brand of multiblock where each block you add to it fulfills a function in the processing of a material.
I.e to make a macerator\pulverizer you need a few blocks making it possible; A buffer holding in the items, for example a vanilla hopper, a thresher block that gets it power from a gear axle, axle motor either powered from a electric grid or portable stirling generator & a collector mechanism.
I think this way is way more engaging than using "magic blocks" and allows for fancier looking factories where there is a reason to build in a specific way.
In a future mod i will most likely implement the concept of freeform multiblock structures. But for now i need to pay attention to my fairies
