Google Desktop has a new version that includes support for Microsoft Office 2007 formats, Windows Vista and Firefox 2.0.
But the most visible change is the new sidebar, that looks much better. You'll find transparent areas, new icons, easier to use options. All in all, the sidebar will look closer to the desktop and the gadgets will have a distinct touch.
"The new Sidebar is transparent, so it fits seamlessly with your desktop environment. Gadgets that fought for attention now look right at home, and content-heavy gadgets get new frames and icons that make it easier to tell them apart. All of this leads to a better place to find your email, news, feeds, stock prices, weather and other essential information," concludes Google Desktop blog.
Another change is that Google Desktop sends you to the cached version if you click on a search result that has been deleted or moved, so you no longer get an error message. The site: operator can now be used in Google Desktop, to search the web history.
It will be interesting to see how many Vista users decide to install Google Desktop. As you know, Microsoft Vista includes a sidebar and has a built-in desktop search. So maybe we can expect more from Google Desktop 5.0.
Google Desktop started as a desktop search tool available from your browser, and became a central point for user's information flow.
