Google Labs Layers

Google Labs is shown in Figure 12-4. It is a collection of experimental features you can turn on and off. They're not always reliable, and they don't always last, but some Google Labs "graduates" have turned into solid and popular features, such as the public transportation directions in Google Maps.

Most main Google products have their own set of Google Labs experiments, and quite often (like in Gmail) those features just won't work on your phone. Google Maps is an exception.

To get to Google Labs, press the Menu button while in Google Maps, and then click More > Labs. You can enable or disable layers at will. Google does use the relative popularity of Google Labs projects as one factor in determining what stays and what goes.

Labs is a testing ground for experimental features that aren't quite ready for primetime. They may change, break or disappear at any time. Click on a lab to enable or disable it.
