Did you know PerlMonks has a "favorites" feature already? It's called your Personal Nodelet. When you first enable your Personal Nodelet, it starts out empty, except for a link (like a button) which adds the current node to the Personal Nodelet.

If you prefer, you can treat your scratchpad as a "favorites" list. The Personal Nodelet also contains links (like buttons) for adding the current node to either your public or private scratchpad.
