If you Google Docs hasn't adopted the new look yet, click on "Try the new look" in the upper right of your documents list.
New Design: The first and most apparent change for Google Docs is how it looks like the new Gmail theme. With a black, white and gray color theme, larger doc titles and larger action buttons (comments and share), the new design is a delight to sore eyes.
Keyboard Shortcuts: Make sure you look at the Keyboard shortcuts for your Documents list - it will make life a lot easier. These will also come in handy when you're using Google Spreadsheets. There are shortcuts for selection, create new, go to, menus and more.
Google Spreadsheets: Copy and Paste Charts: Use Google Spreadsheets for presentations and data visualizations? You can now easily copy and paste charts from a spreadsheet into a document or drawing to share your results in any document form. Here's five easy steps on how.
New Charts: Whether you're a bar graph type of person or are partial to pies charts, Google has a wide new offering of different charts to choose from. Candlestick, motion, annotated timeline, you name it.
Teamwork: Lastly, if you use Google Docs with people you work with, now you can see which object a collaborator is selecting in drawings. Comments and discussions has also been improved and personalized with time stamps, profile pictures, comment resolution and integration with email.
Hope the new Google docs helps you work more efficiently!
