I'm just curious if you could potentially make a configurable list, in a similar fashion to the configs for the mods Poor Ores and Dense ores to make it easier to add/remove ores you can sift for. I'm aware that it would probably require it to be its own config file, and that it would be a little more work on the part of the person doing the configs for packs, but overall I feel it would be a pretty nice addition.
