One of the secrets, or "seecrets" revealed. If you press F3, you'll notice the coordinates your facing is highlighted. This helps you find put which direction your going. Also, you'll notice your crosshair is colored red, green, blue. Red, tells you how far you are going to the East, or West. Green, which tells you how high you have ascended or descended in the Y coordinates. And blue, which tells you how far you have gone North, or South. That's all the secrets I know of as of now. I'm not sure if this was a secret or if it was already in the other snapshot. One last thing, you'll also notice it says in the picture "Towards positive X"...
