Google Maps shows a new link at the top of the screen called "Saved Location". This feature is available in all Google Maps versions.
You can save your searches, add a label to the locations, choose your location by default. Google Suggest is built-in: in this example (screenshot), if you type "G", Google Maps allows you to select directly Googleplex or Google France.
These features have already been available on Google Maps' competitors for a while...
