+1 as well.
Maybe they could implement it sort of how crafting is done in Graveyard Keeper. You could queue items you want to craft, then just long press E to work on it. There's a progress bar until one (or one set) of item(s) are done crafting.
Alternatively, you could just choose to craft more than one then just wait for your character to craft them by themselves (instantly, or after a second or two).
