It's been barely a month since Google Docs on Android got offline support, but here comes Mountain View with another equally impressive update. Those upgrading today are treated to collaborative editing, much in the vein of their desktop counterparts. That means you can now watch edits happen in real time from your Android tablet or smartphone. In addition, there's a bevy of interface tweaks too, including a new pinch-to-zoom gesture and rich text formatting. Feel good video demoing all awaits after the break.
