I’d like to see research come into it. It’d be very cool if every crafter could be instructed to research. They would tinker and use up resources, and figure out how to make better things. After all, if you’ve just been promoted to a carpenter by being handed a saw I’m sure you’re not going to be making wonderfully carved chairs without a few trials and errors!
It wouldn’t have to be a steep gameplay slope by any means, but it would mean you would have to have a base level of simple resources and amenities secured before the player might feel up to spending time and resources dedicated to discovering new items.
