A nice mod to have for deco. The target is

• separate the markings in the mod into several categories, with each of them containing less then 60 items (that's how large a chisel group can get at most considering the amount of the slots in its GUI).
• adding curving group for each of them.
• for each group, add 1 recipe so you can actually craft them. (better if the recipe is gregic)

This is fixed by #1502.
