Original issue
BluSunrize/WitchingGadgets#66

Is this something that can be added here or are we needing to wait for the mod author to add/change something? If something is needed on the other side, what would it be that is needed?

WitchingGadgets has native support for MineTweaker, so new functions / commands should also be implemented directly in the mod.

Witching Gadgets MT support has nothing to do with Modtweaker, and is housed entirely in WG itself.
