Kind of a small suggestion, but it nice if we could macerate Glowstone Blocks into 4 Glowstone each, it would allow us to store large amounts of Glowstone Dust (In it's block form), and not risk losing any when breaking the blocks to get the dust back.
Edit: You can make Glowstone from UU-Matter, but not dust, and you can lose up to 3 dust from each block if you break it.
