It's rather simple. It seems somehow a waste that every Ore has it's own BlockID. I wonder if there is a reason for this or if you could merge them into one ID with several Damage-Values. It seems changing the ID of Ores is possible and BC switched IDs without breaking Maps too, but maybe there is a reason for this.
The second Question is in regards of the Macerator and similar machines. It is possible to consume two or more items in one cycle? Actually the macerator macerates everything into one or more outputs. But could it also provide one output while using up more then one of the input items (like compressing 2 dirt into cobblestone just as an example).
The third question is about the time needed for one cycle. It seems that some processes take longer then others. Maybe it's an illusion because you have to wait for your rubber etc. but is it possible to make different processes cost different amounts of time? (Like I-Diamonds take longer then compressing sand to sandstone)
