An option to disable specific items from the mod would be wonderful.

I tried using Item Obliterator to disable what I didn't want.

A lot of items in your mod share the same ID though, and I'd have to use the NBT tags. While Item Obliterator does support NBT, I have not had success with this, which probably stems from the NBTs for your items being very long.

If you decide you want to implement this, a perfect example of how you can set up configuration would be the Epic Knights mod.

Disabling items in their config is as simple as a toggle. Doing so even removes those items from the creative menu, which is exactly what I'm looking for, as I'm working on a creative pack atm.
