Sharing links on Mento with Opera
(jump directly to the button, to the sourcecode or take a look at the screenshots)
If you are using 
Opera and Mento you probably looked for better integration of Mento with Opera.
Some months ago I created a button for better integration of del.icio.us with Opera, now I did the same for Mento. But in this case it was easier because the Mento bookmarklet already uses the current selection as comment. Because of that I didn't do anything besides wrapping some Opera-specific code around the bookmarklet.
So enjoy the "Share with Mento" button:
Share with Mento
Share with Mento
(to install the button just drag the link up to your personal bar - You can choose between two icons: the "compose mail" icon and the "add bookmark" icon)
Sourcecode
opera:/button/Go%20to%20page,
%22javascript:
javascript:void((function(){
var%20e=document.createElement('script');
e.setAttribute('type','text/javascript');
e.setAttribute('src','http://www.mento.info/qp/mini/run.js');
document.body.appendChild(e)
})())%22,
,%22Share with Mento%22,Compose%20mail
(to use the "new bookmark" icon just replace "Compose%20mail" with "New%20bookmark" - you may also use any other Opera icon here, you only need to get to know the correct name)
Screenshots
Tips and Tools for Sharing opened in an Opera window. The "Share with Mento" button and the corresponding tooltip are highlighted.
After clicking the button the usual "popup layer" opens.
