Biped plots have four available workshops in the small shelter format:
Paper Press for the Scholar School
Pottery Table and Kiln for Tinkerer's Key Molds and (as I recall) some Festival Foods
Distillery for plots having a Leatherworking Shop and no Confectioner Shop
Cauldron for plots having a Confectioner Shop and no Alchemy shop
I suggest that the game would be well served to have a Millstone in a small shelter format. Such a workshop would be welcomed for smaller plots having Confectioner Shop and/or Alchemy shop where space is at a premium, and for any such plot for which a rather large Windmill Structure detracts from the overall plot design appearance.
Accordingly, may we please have a millstone shop in the established small shelter template format?
