Just a few suggestions as I played with the mod.
I mostly use this mod with other similar mods and thus making most of the crafting item bonus non needed, since others perform the same function.
So maybe it would be nice to fill in that gap and make this mod on par with others.

So what I am suggesting is to add curios support to the bags, add a builder's wand as another builder item, And for the miner, maybe add a massive fortune or the Luck effect from time to time.
