While I'm up to speed, here are a few more late Christmas presents!
There's a new ruler tool, which is enabled using the compass icon, which can now be found just below the PHG circle icon. The ruler calculates great circle distance and direction between two points. Multiple rulers can be added by clicking on the compass icon again. Clicking on a ruler endpoint marker will reveal the coordinates and address of the marker position.
Furthermore, after clicking on any target on the map, an address will be shown, if possible. The address is obtained using Google's reverse geocoding service. The service may or may not be available in your area, and the data is received with a small delay after the info balloon is first opened.
