NOtary Rated 5 out of 5 stars

A great idea. So simple, and yet so convenient. It adds an additional pane to all messages (interestingly enough including RSS feeds) where notes may be typed. No saving required. Only 2 buttons on the pane. One to delete the note and the other to search - which I can't fathom out how to use. Still, you can't expect everything. Maybe the developer will suggest how ? All in all the add-on does what it sets out to do with a minimum of fuss.
