Google has released version 4 of its new Toolbar, still in Beta. You can read about it and download it from this PC Magazine site. A couple of quotes from the review:
With this version users can add custom buttons that will either search your favorite site without your having to go there or take you directly to it. A drop-down menu on the button itself can even reveal the latest headlines from that site.
The new Send To button lets you share pages via blog (you need a Blogger.com account), e-mail (you need a Gmail account), or text message (SMS). There’s also a Gmail button that can replace the Gmail notifier that sits in your taskbar.
