If you have the mats on hand, I don't see any reason why you should have to manually craft each item unless you're trying to HQ. I don't support being able to have stuff crafted while not in game, but like, if I have mats for 100 ingots, I don't want to go through what's currently a 15 second process just to open the crafting interface just to hit Hasty Hand.
Just set a limit on how high the recipe can be vs your craft level to auto-craft. For stuff like materials, I'd want to see an interface like WoW's crafting, where you have x amount of materials in your inventory and you just hit a craft button and watch them go.
