Presenter View allows you to see your notes on your monitor while the audience only sees the slide. It automatically adapts to your projection set-up, and you can even use it on a single monitor.
Themes now come with a set of variations, like different color palettes and font families. And, PowerPoint 2013 provides new widescreen themes along with standard sizes. Choose a theme and variant from the start screen or from the Design tab.
Now you’ve got several ways to share a PowerPoint presentation over the Web. You can send out a link to the slides, or start a full-on Lync meeting that displays the deck with audio and IM. Your audience can join you from anywhere, on any device using Lync or the Office Presentation Service
