Today Google quietly updated Gmail Toolbar. The new toolbar is looking good. At the right top side you can see significant changes. Now you will see only your name, If you click on it, a drop down window shows the accounts integrated with your Gmail id. At end of the end of the top right corner you can see gear icon, just as in the Chrome Browser which will gives you Mail settings, Account settings, Labs etc.
