Hello

It would be good to include the ability to add audio to the presentation.

I think that could be up to two paths "compatible"

1 - Adding live audio from the presenter as you will progress in the presentation (live audio stream)

2 - Add an audio track to accompany the presentation for autoplay.

Today is possible by 'youtube' do something similar if you record a ppt and add the audio, what I see as an opportunity is in the "live presentation" and you may have several spectators from different locations following your presentation in an agile and fast without losing the interactivity with the audience.
