Google announced that Docs is now officially integrated into the core Google+ Hangouts experience by allowing users to collaborate on documents from within a hangout. The feature essentially adds video chat capabilities to the web-based Google Docs experience. Up until now, the feature was only accessible through “Hangouts with extras,” an opt-in preview of scrennsharing, Sketchpad, and Google Docs integration. To use the new feature, simply click the “Docs” button during your hangout. The other features included in the preview have not yet been switched on for all users.
To try it out, just click on the new “Docs” button inside your hangout:
- you can add an existing document, or upload a new one
- added documents are available as a list on the left-hand side
- you can switch between and collaboratively edit multiple documents at once


Not many people are on Hangout n Google has come up with this, It's nice though but their are some basic issues with Google docs which has to be solved. Issues concerning sharing a portion of a Google spreadsheet with your team members. There is no way I can do it without copying the data and pasting it on a new sheet. This increases redundancy. There should be an option where I can just share a part of my spreadsheet – isn’t it?
I hope Google should solve these issues, well I have heard about some tools which says they are better than Google docs when it comes to sharing. It's CollateBox http://www.collatebox.com/ gotta check out this one..
