Somehow, I assumed "Notes" would be "notes for this page". But, it's just a notepad...no awareness of where I am. That's much less interesting/useful than I thought it would be.

Is there a browser plugin out there that provides a notes sidebar for the page you're currently on, and allows flipping through the notes with a link to the pages they relate to? Because that'd be awesome. Googling only reveals some kitschy "post-it on a web page" type note things, which is definitely not what I want.
