Lab Users will see a redesigned user interface for Google Docs over the next several days. One of the most helpful changes is the addition of a preview pane on the right side of the screen. Filters that allow document selection by the manner in which they are shared, sorting options, and more convenient ways to keep your documents organized highlight the changes. For more information, check out Google's Blog. In a prior blog post, Google added the capability to upload and play videos.
If you have never used Google Docs, consider reviewing some of the older YouTube video's that explain how they can be used.
