[Enhancement] Equip slot

[ronyan149]

Is it possible to add an 'equip slot' option for each type of item? It would be great if we could create various auxiliary gem items, etc., that can be held in the off-hand to boost stats, attributes, passive skills, etc., in support of the main weapon held in the main hand.

The item types can be anything in Minecraft: blocks, materials, etc.

It would also be helpful to add a few more options such as: disable/enable placed, disable be enchanted, disable be crafted, to prevent the loss of these items.
