Opera quick proxy toggle button

If you use Opera and need to easily and quickly toggle on or off your proxy setting, much like Firefox's QuickProxy add-on, you may try this. Point your browser to this URL:

 opera:/button/Enable%20proxy%20servers,,,%22Disable%20Proxy%22,Expand%20Enabled%20%3E%20Disable%20proxy%20servers,,,%22Enable%20Proxy%22,Expand%20Disabled%20+%20Show%20preferences,22,Proxy%20servers  

Then accept the installation and drag the button where you want. Clicking on it will toggle the proxy on and off and a long-click will bring you to the proxy configuration menu.
