is there any addon that lets you add annotations/notes for a particular part of a web page, and is able to save the annotated page as html files to your hard disk? ScrapBook lets you add sticky annotations and mouse-over tooltips, but it's not very flexible. I'm looking for something that is more like an on-the-fly WYSIWYG html editor that is also easy to add annotations.
This would be very useful when doing research. Thanks!
