This game is awesome, and I can't wait to see what future updates will bring. Just some ideas:
add wheelbarrow: can be used to carry a larger quantity of items. (crafting: like one wheel, four planks, and two poles)
add railroads and carts: can be used to automate the transport of materials
add maybe some way of using the Folk to help you, cause they need to get up and do some work instead of laying there all day :D
