Here's a big collection of javascript fragments designed to be run from a bookmark to edit in situ the page you are on. Or you could embed them in pages to make them change when activated, as this site does for demoing them. Try going to the zap page and playing with those to get a feel for what they are good for.

Suddenly bookmarks from a context menu seems much more useful.
