If you tap the upper right corner of the map window, it will change to a 'radar' - This will show you which way the craft is pointing in relation to the direction you are facing.
It's very useful if you are in a position whereby your Mavic is too far away / small in the sky to see which way it's oriented. i.e. if it's pointing the same direction you are facing, then it will get further away from you if you give it some forward stick. However, if you yaw the craft so that it is pointing towards you, then forward stick will bring it home.
