Shields will auto equip when you hold a sword, and auto unequip. Torches will do the same with pickaxes
Description
If you have a shield in your inventory, then hold a sword, it will auto equip the shield to your offhand. Then when you stop holding the sword, it will automatically unequip the shield from your offhand. This does the same thing with pickaxes and torches.
There are config options for adding your own interactions.
