The current experimental build is getting rid of refined iron, which leaves those of us who made a bunch and then updated with some pretty useless items. Could a simple crafting table recipe be added that turns refined iron back into iron?
Also, I was thinking it would be cool if the compressor could make gravel into cobblestone. I've already produced more flint than I could ever possibly need, but with the Millenaire mod, I can always make cobblestone into stone and sell it to the villages.
If I think of anything else, I'll post it here
