Hi again,
today I noticed that your bookmarklet now supports to use the current selection as comment. That is, why I finally decided to do for Mento, what I already did some months ago for del.icio.us. I created a "button" for Opera.
In this case it wasn't much more than wrapping some Opera-specific code around your bookmarklet.
The result is:
(to install the button just drag the link up to your personal bar)
The code is simple and easy to understand:
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,New%20Bookmark
(the last part which is here "New%20Bookmark" determines what icon will be used for the button)
For more information see
Posting links to del.icio.us with Opera (I have to upgrade that page, still old Opera screenshots ...).
Please tell me if You plan to include that in your official site, because if not I'm going to set up a page like the one linked above.
Best wishes,
Götz
