We use bridge for our financial reporting process which allows us an easy way into accounting information with minimal disruption in workflow flow due dates etc..
It's very intuitive once you get used it but I think we are still looking at some ways that would make navigation easier especially when there may be more than one page open (ease new user experience). Also sometimes if two or three pages have been opened then switching back between them requires hitting "back" several times before bringing up where they were last time! This will likely improve over future updates as well since this has always existed though maybe not known about by all current customers/users?
