This is a feature I am hoping for - ability to have synchronized videos alongside slide view.
If you want beta testers, I'm in.
You can currently do that in a way. You can read about it here: http://blog.slideshare.net/2010/07/07/synchronize-your-presentations-with-your-videos/
Thanks. That looks promising - actually exactly what I'm asking for. But the pricing is steep and maybe a bit unpractical for us. There should be a category between free and premium that excludes ads but still uses Youtube or Google videos. I'll look into this later.
