I haven't made it to the testing this mod yet, but there are few things I'd like to share.
When the mod crashes because of ID conflict, id does write NOTHING to its config file, so player have to create new instance of MC only with IC2/core and the mod to get a config to edit. Now the config itself, sections named "1" and "2"? Something like "Blocks", "Items" and "Other" would be much better (now are blocks mixed with other options).
