The result of fascination of Google Maps v3 upgrade and OOP structures of prototypes in JavaScript that I wrote before ended up with a small Overlay class for Google Maps.
Zone class allows easily create dynamic polygons based on built-in polylines of Google Maps, and easily save areas using jQuery framework and its jQuery Dialog window.
All the details are on GitHub repository, so feel free to share comments and/or issues on the code structure/errors.
Stay tuned!
