QuoteOne feature that I think would be -extremely- useful would be expanding Forge’s ore-dictionary to using the same damage ID multiplexing Redpower2 currently uses for ore consolidation. Add new ‘ores’ seems so common, in fact, that I think it would be a huge benefit if Forge not only handled allocating IDs, but also populating ranges with various density of ores. The interface should clearly have populating ores as a second step. This way ranges, possibly even overlapping, could be provided. (Eg, chance 1/20000 of a run length of up to N between 1 and 64 + 1/1000 for 1:40 + 1/250 for 1:20)
It would also be awesome if the Ore Dictionary would store it’s configuration in a config file so that administrators might pre-assign ore names to IDs, and even over-ride mods from being able to add ores via this interface (so that administrator selected rules could be used instead). Further it might also allow for adding more vanilla resources in similar ways (e.g. more iron or diamond; in case you wanted to simulate a completely different type of terrain).
