Google's new feature in SERPs "Google Notebook"

It’s been nearly four months since Google let Google Notebook out of beta, but it was just today I noticed that they’ve integrated Google Notebook into search engine results pages.


Click on the “Note this” link and the text changes to read “Duly noted” (which I do think is just a little cute) and pops up a Google Notebook window.
In the Notebook window, you can add comments to your saved search results, create new notes and comment on them, and manage various notebooks.
We would think that creating different notebooks for different research subjects would be pretty handy. One note for improvement to make the Notebook window draggable. For the life of us, we can’t figure out how to move it anywhere but anchored to the lower right part of the screen.
The “Note this” option seems to appear only when you’re signed in to Google.
