Override power settings

It would be nice, particularly when in a SlideShow mode on PowerPoint, that the power settings of the iPad--screen dimming and sleep--could be configured to be overridden in CloudOn. If I am giving a presentation using it, and need to discuss a slide for a few minutes, I need to constantly tap the screen to keep it awake, which keeps me pretty close to the iPad. I know other apps can override this, so it would be nice if this was a configurable option for CloudOn, even if it cannot be specific to SlideShow mode.
