For all you Inernet Explorer users out there, Google just released the new Google Toolbar Beta (the fourth one) which has some pretty cool features. IE users have not been able to benefit from the slew of plugins that Firefox users have, which is a void that Google has been able to fill a bit with the new toolbar. The new toolbar has some great new features, the most interesting being user defined buttons. With a little bit of XML knowledge you can build some really cool custom functionality. The new toolbar also has a bookmark manager, an auto complete feature, and the ability to easily share web pages via email. Google guru Matt Cutts has a very insightful review of the new toolbar here.
