The Disenchanter is supposed to work like so: enchanted items go in, unenchanted items and enchanted books go out.

In practice, however, items with multiple enchantments are only stripped of one of them before being directed to the “Unenchanted Items” slots. I think it would be much more convenient for items to be processed repeatedly before moving to that slot. An item shouldn’t be output until it has been processed enough times to remove all enchantments.

This would be extremely helpful for more basic automation, such as using Hoppers or some other buffer system that can’t cycle output back through again.
