I'm looking for an on-site bookmark script. Meaning the link would be stored as a favorite on the site itself, not as a browser bookmark.

Let's say a visitor likes a page and wants to have a link to it for quick reference, but doesn't want to bookmark those pages in his browser.

There would be a '+' button or 'add as favorite' button on each page. When the visitor clicks that button, the URL and pagename would be stored in a cookie and displayed on the sidebar menu of the site.

I've been searching the Internet for a script like this, but the only thing close I could find was a "Last Visited Pages" javascript. But that stores last visited pages in the sidebar. I want the visitor to have control over which pages are saved.

Hope my question makes sense. Thanks a bunch for your time!

EDIT: all pages on the site are .html files
