It'd be nice to have more "pack" types such as a "Stone" pack generator that generates a raw stone, and optional cobblestone, polished, and brick variants, along with stair/slab/wall variants and respective crafting/furnace/stonecutter ecipes.
I'd assume this is already planned, but if not, I'd just like to suggest it, as I'm trying to add more than one stone type to my mod and I'm having to make several dozen mod elements that are mostly redundant recipes. And that's for one type of stone, mind you.
A "Tree" pack with wood, leaves, and planks would also be nice, now that I think about it. It'd really streamline the process and get rid of the tedious bits of modmaking.
Thanks for listening!
