Google Desktop 2, a free downloadable application, combines desktop search and the Google Sidebar, a floating tool palette that offers personalized news and other information based on a user's habits.
Dozens of new third-party Sidebar panels are now available like iTunes, Winamp control and an American Express panel to track and view credit card transactions in real time. The new software can also display maps related to the sites one visits while surfing the Net.
In addition, developers can use simple JavaScript to write plug-ins for Google Desktop 2.
