The Maps app is good at showing me where I am, but I don’t know how to use it for more than finding out my current location. What’s that little arrowhead thing with distance measuring? Can I measure distance between two points on the map, or my current location and somewhere else? Can I get it to show me my latitude and longitude, or display a map at a particular latitude/longitude?
Is there a user guide somewhere that explains how to unlock all of its capabilities?
