This might be an elaborate feature, but I think it would make the application absolutely killer, and remove the need to make screencasts for everything one ever does.

It would work like this: In addition to creating the slideset, one could upload an MP3 file or similar, which contains whatever voiceover one needs. Different cue-points in the sound file (just time-markers, basically) would map to slides, which the visualization engine will then transition between. In other words, the HTML engine will automatically page as different parts of the audio presentation is reached.

Similarly, manually flipping between slides will automatically make the audio file jump to the corresponding time, so that the audio presentation and the visual presentation is always in sync.

This would allow people to make completely fully featured automatic presentations with guidance in addition to having quick access to the different decks for browsing.

I would easily pay double for PRO for this feature. Thanks for listening.

If my explanation is unclear, imagine a cross between slid.es as it is today and an application like Soundnote: http://soundnote.com/

Thanks for listening!

Below are the two problems:
Problem 1 )
I would like to add the support for mouse scroll to navigate through slides.

Problem 2 )
Below is the existing layout of slides:
1 4 5 6 7 8 9
2 4 5 6 7 8 9
3 4 5 6 7 8 9
10 4 5 6 7 8 9
11 4 5 6 7 8 9

But I want the layout of slides to be like below:
1
2
3 4 5 6 7 8 9
10
11

(Where numbers represent the rank of slide in sequence)

Please help me.
