Please upgrade to 2.2 here.
The 2.0 and 2.1 branches are no longer being updated.
This discussion is related to the Vanoogle
i'd love if this could be integrated more seamlessly into the vanilla interface. perhaps if it could replace the default vanilla search box easier, and without the 'close' button there (instead put the close button on the popup)?
also if the plugin could stick the search box code where the theme is sticking the vanilla search box, it would help with positioning.
