It would be great to have the capability to record audio
to go along with each slide. The user could have a
toolbar for audio with UI controls that allow them to
start recording, stop, play, pause, and erase.
It may make sense to have an option to let the user
decide whether or not they want to continue a recording
across slides ~ meaning if the user is trying to narrate
an idea and more than 1 slide is used to illustrate a
single point it may make sense for the audio to 'span'
across slides vs. be broken up into sound bites per
slide.
