"Raven uses a technique called "site specific browsing" to create a dedicated browser instance for certain websites and their features. It debuts with the most widely used websites including Google+, Facebook, Twitter and Quora. Within each app Raven provides yet another instance for key features. This provides a whole new level of multitasking within a single window. The Smart Bar unifies navigation across many different websites allowing access to features quickly, without effort and with little instruction."
I have no clue what this means. This clearly needs to be dumbed down to be understandable by average users.
