I don't really want to send anyone my web searching history, however I would be interested if the plugin could export data to csv,xml or json. That way I could datamine my search history with whatever tools I like to use.
By the way, you could build a web app that runs on the desktop with Appcelarator's Titanium, or port the existing one to Titanium.
If you want us to let you know when we have something together (probably less than a week), my email is in my profile, shoot me a note, if you'd like.
