Google Docs for Android Refreshes Editing Tools

Nice to see this app. Would be very helpful to many of us. Meanwhile, I've come across some new tools which looks very interesting and handy, for collaboration .
One such tool is CollateBox http://www.collatebox.com/ . Just registered with this one found their video looks neat..Eagerly waiting for this one.
