Suggestion for Advanced Dual-Monitor Presentation Mode Features

Not sure if someone has recommended that already or Gamma is on it. Anyways, here my 2 cent: Advanced dual-monitor presentation mode. I am sure you know this already. I was sitting in the boardroom and launched my deck to present a few ideas. It would be great to be able to select another card/slide if I am running out of time or decide to present less cards/slides. Just think like "PPT BUT BETTER and different". And I hope you have started coding ;-)
