This is a neat add-on when you want to make sticky-notes on a page you’re visiting, then view the sticky note when you return to the page at a later time.

Very useful for designers / programmers – you can make notes on a page while talking to your customer, or for any web-based business tool, where you want notes about, say, a customer profile, but only available to you.
