Google has just updated document files in Google Drive to add some Google+ integration and also make conversations much easier to begin.
First off, you'll now see the Google+ profile pictures of everyone currently working on the document right at the top. Before, it was just the names that appeared. If you hover over the photo, you'll see a small snapshot of their Google+ profile pic, complete with details. From there, you'll be able to add them to your circles without ever leaving the document. It's a small, but useful update for those who use Google Drive to collaborate on projects.
Starting a group chat also got easier with today's update:
"In addition, you can now start a group chat with just one click. Simply select the new chat button at the top right and a chat box will appear, making it easy for you to quickly message everyone in the file," says Google software engineer Eric Zhang.
Google says that you should start seeing the new features in your Drive documents today or tomorrow. Also, in the future, Google plans to add these new features to other types of files, like Google Sheets.
