Panic Demos 'Coda Notes' Extension for Safari 5
Just hours after Apple released Safari 5 with support for extensions created by third-party developers, Panic has demoed 'Coda Notes', an extension allowing for website annotation and sharing.
When you install Coda Notes, you'll get a new button in your toolbar. Click it to see all our annotation tools, built right into Safari. Draw some notes on your favorite website. Communicate changes, ideas, concepts, or problems. Then, when you're done, hit the Send Notes button and the whole page flips over as a postcard.
