To allow players to interact automatically with their inventory, there could be an option to equip or unequip an Extended item.

• Equip would ask for an item ID and a slot (optional coordinates/stance if the item is wearable to set that automatically as well ?), and would equip the first item it finds with that ID in the player's inventory.
• Unequip would ask for a slot (or an item ID, maybe) and put the item in the first empty inventory slot, if the inventory isn't full.

Related to this, we could add item events "On equip" and "On unequip". I also need to check if the item count condition allows to count in Equipped inventory only (to check if an item is equipped, for instance).
