Google has just launched Google Desktop 3 beta. This new version of their desktop search tool has new features that make finding and sharing information even easier and more fun than before, they say:
As a Sidebar user, you can now customize and view personalized information anywhere on the the desktop by clicking and dragging your favorite panels wherever you like. Furthermore, you can now easily share information from your Sidebar panels with your contacts by sending it to them through email, chat or directly to their Sidebar. As an added bonus you and your contacts can also play online games through the Sidebar.
We also provided the means to access your data no matter where it resides. The Search Across Computers feature makes it seamless to search the content of your documents and web history from any of your computers.
Other new features include the addition of a Search Lock, an advanced search form, spelling suggestions, zip file indexing, and an improved preferences page.
Google also made a few APIs and tools available to allow programmers to develop applications for Desktop. You can download it here.
