Just a shortcut to Chrome settings page
This is just a shortcut to Chrome Settings, nothing more.
When installed, it will add "Settings" icon to your browser's toolbar.
Click the icon and you'll open Chrome settings page.
And that's all this "extension" does...
(There are, however, some options available: you can set the button to open the settings panel in new tab or in the current tab and, if you want, you can add it to the context menu.)
