Ok, so I like the belts, but I find them kinda ugly when using them to transfer rotation over distance, and shafts can't go diagonal.

So my suggestion would be that for 3 dried kelp in a line you get a serpentine belt/drive belt that looks less wide and only transfers the rotational force and not items.

if you use a casing on a belt it will look better. (i prefer brass casing it looks best to me)

It would be wonderful to use on two adjacent shaft end to connect them without use extra blocks.

Ex: connect two adjacent belt
