The Google Docs app for Android has received a substantial update today, adding some significant new features which to bring the phone and tablet app in line with the full desktop version.
First up is collaborative editing, which allows multiple people to work on the same document in real time -- this has long been possible on the desktop, but has been lacking in the mobile app. And it's also possible to set document permissions and invite others in your address book to work on a document alongside you.
In addition, rich text controls are included for documents, and pinch-to-zoom now fully functional too, making possible to manipulate text, undo and redo just like in the desktop version. Unfortunately these new features only work in documents, not spreadsheets, but regardless, it's a big step forward for the mobile version of Docs.
We've got Android Market links, and an official introductory video, after the jump.
