Google has just updated its Gesture Search application with proper support for tablets, including the Nexus 7. If you haven't used the Gesture Search app before, its a pretty interesting concept. Similar to what Google has been offering on the mobile view of it's search page, Gesture Search lets you spell out words by writing on the screen one letter at a time, and then instantly returns search items. You can choose what sources to search -- such as contacts, browser bookmarks, apps and more.
In addition to tablet support, Gesture Search now offers compatibility with even more languages. Simplified Chinese, Dutch, French, German, Italian, Polish, Portuguese, Russian, Spanish and Turkish are now supported as of this latest update.
Gesture Search is useful for when you've only got one hand free and need to make a quick search, though it's not the most high-profile Google app around. Take a look at the Google Play Store link above and try it out for yourself.
