Google has mentioned in its Google Docs Blog that seasoned presenters keep their slides simple and use slides to help illustrate their points, not to present all of their information. They jot down their talking points, examples, and supporting evidence in speaker notes. To help you do this in Docs, we’ve added speaker notes. You can print these speaker notes in advance, or pop them up in a separate window when you present. This would be a wonderful add-on to the impressive Google Presentations.
The new option to embed YouTube videos directly into presentations would be extremely useful on the internet while sharing presentations online using Google Docs users.
