I was thinking a bag because i craft in containers a lot to either keep it all contained separately or to quickly dispose of when crafting for skill gain. Would be super nice for the heartwood crafting quests and it would help a ton if it worked for filling bods too. Put ingots in bag, craft the desired amount, click the combine with bod button and target the bag. I guess I'm trying to eliminate as much mouse clicking as possible.
Ya I think stacking would be best for the quest items as it would massivly save on storage and you would still only have to click 1 item (the stack) to toggle it as your quest item... But I would LOVE to have a bag for BODS. I have been thinking the same thing for a while now, well almost. My idea was that they simply give us an option on the bod to click... "Make Needed".
Just like they have the "make max" or "make quest item" options in the crafting gump. Let us open a Bod, and click the button, and your crafter will make the items needed and they go automatically into the bod as they are made. That would save a TON of clicking.
So if you have a "20 Exceptional Leather Tunic" BOD... you simply open it and click make needed... it will then open your crafting tool and start pumping out lether tunics... everytime you make an exceptional item it goes directly into the BOD, if you only make a normal item it goes into your pack. Easy and effective.
