My suggestion is to add a quality of life command which is just an upgrade from /smelt. This doesn't effect core gameplay much but as I said just a QoL update that some players might appreciate. The command smelts all "smeltable" items in your inventory as opposing to using /smelt a bunch of time and spamming the chat.
That command already exists, but it's a separate command (/smeltall) instead of being a parameter to /smelt.
