Alright, my suggestion is a pen and ink. The way they would be crafted would be 3 feathers in a vertical line for a large feather/pen and 3 smooth stone in the same formation as a bucket for an ink container. Feather has a certain durability and container has no durability (but the ink in the container would run out. A new item would also be colored ink, which would be crafted by putting an ink sack in the center space and to the left and right would be the desired dye, and it would create two colored ink of the dye you used. To put ink in the container you would place the container under the ink. You could also use the container to hold a water source (can't be re-placed!) this is useful for removing the color on your pen. O.k, here comes the good part. If you place a feather in a crafting bench with a container that has ink, it will get the ability to mark maps, by right-clicking the feather, then left-clicking the map while they're in your hotbar. You could trace around the map with your feather to show the location of important things and how to get into hidden places. Could someone think of some type of eraser?
