I've found that some people get lost at what axis you are applying the value for in logic for Motion Actuator, so i whipped up this handy label last night,
It basically helps the new user to know what Axis they are putting the value for the values
i think its a fairly useful addition to the User Interface for people especially in a learning environment like a school, Uni, or anywhere

Hope this is useful for anyone!
