 ## Interface
 - Inventory: Hold down right mouse button while holding an item stack to drop items into the slots as you move the mouse. Makes crafting MUCH faster

 #### Nice-to-haye
 - Utility function to rotate pillar-like nodes, requiring only 3 possible orientations (X, Y, Z). Basically this is `minetest.rotate_node` but with less orientations; the purpur pillar would mess up if a mirrored rotation would be possible. This is already implemented in MCL2, See `mcl_util` for more infos
