Coda Notes is Out
One of the interesting demos at WWDC 2010 was in the Safari Extensions talk where Cabel of Panic fame showed something they hacked up called Coda Notes. It's a way to annotate a web page in Safari and then email it to your support staff, etc., and they can see all your annotations. This is super helpful for the web developer, and while I'm not sure I'll use it a lot, I certainly want to keep a handle on it. It looks just too amazingly powerful.
Awesome work.
