I've had the pleasure of using this mod on other servers and it is quite handy.
It allows for you to repair items and keep enchantments on the Item.
For example: You can repair a nearly broken Iron sword by right-clicking on the anvil (Iron block most of the times). If you have iron ingots in your inventory, then the sword will be repaired at the cost of 1 ingot per use. So 2 iron ingots will fully repair your sword and it saves the enchantment on it.
Just a small suggestion
