Here's one new feature rolling next week among many on the latest Beta Channel: the Chrome Launcher 2.0.
This new launcher is the best way to start new activities on Chrome OS, like performing a Google search or launching apps. It's fast, simple, and helps you get things done. Search has been enhanced to help you find what you are looking for faster, apps you most often use right have been put at your fingertips, and the power of Google Now has been brought to your Chromebook.
