Enchant tips/testing enchants when using Anvil.

This should be an add-on in all MC versions.

Since enchantments are a fundamental base for combat and mining and also exploring at a higher level, anvils are highly used in mid game and end game level, therefore the cost level is a very delicate situation as there is a level cap for enchanting aka the infamous "TOO EXPENSIVE" which leads many time to the ultimate tool/gear be unable to be completed many times.

My suggestion should be when using the Anvil,  next to it should have some information about the enchantments that can be apply to the tool and which combinations are not possible.

A filter for testing the enchanted books you have, the cost of it and if the books you have will be possible or it will trigger the TOO EXPENSIVE level cap.

This would allow players to safely and effectively enchant their gear to what they desire without waste and properly enjoy the game to it's fullest without making preventable mistakes.
