I would LOVE to see DIFFERENT TYPES STORES in towns or by specific location (by water, mines) to BUY COMPLETED CRAFTED ITEMS like a HOME FURNISHING STORE that has Beds, Carpets, Showers, Tvs etc. A CLOTHING STORE with all armours WEAPON STORE, PET STORE, GARDEN AND LAND SCAPING STORE, GROCERY STORE, OUTDOOR STORE, TOOLS , and even a BLOCK STORE to buy that last block you need to complete a recipe or design. You get the idea. Currency could be EXP, Gem Blocks or Ingots that give monitary value by type used.
OH YEAH ALMOST FORGOT BLOCKS THAT ARE RAMPED SHAPE AND BLOCKS ABLE TO BUILD REAL ROUNDED EDGES
