it would be nice to have

listItems(),
listCraft(),
listAll()

return the ItemID along with the other info it returns so that there is a way to get an ItemID from its name inside a program, it already returns the Meta for the items so unless there was a reason itemID was no implemented that im not aware of i think that this would be an amazing addition to the returned data :)

this was related to the whole item name being the ID thing...

I'm sorry, I'm not sure what you mean. I'm not sure about listItems() and listCraft(), but I know that listAll() already includes the ID of the item. Am I misunderstanding?
