A tipster over at the Google Operating System blog pointed out a small —but welcomed— tweak in Google Maps that lets you highlight areas of interest based on upon search queries:
When you search for a city or a county or a ZIP Code, Google Maps now highlights the boundaries of what you searched for. If you are zoomed out, the whole area is shaded pink. If you zoom in a bit, it has just a big pink border with grey shading. Zoom in even more and it’s a dashed boundary with grey shading.
In the above screenshot, I searched for Cupertino, Calif., and Google Maps automatically highlighted the city’s area inside the map view, allowing me to visually grasp the size of Cupertino. Note that the highlighting feature does not work in other Maps views, such as satellite.
