Feature Request: Variable Playback Speed

I recognize, from the answers to previous questions about this topic, that variable playback speed is not currently possible in Storyline and is not on the development roadmap.  I'm going to suggest that this is shortsighted.

Learners are demonstrating their preference for and use of time compression on other multimedia platforms -- see http://www.theatlantic.com/technology/archive/2015/06/the-rise-of-speed-listening/396740/ -- and research shows that, other things held equal, time compression does not have a detrimental impact on comprehension  -- see http://mattinouye.com/post/148068113951/speed-listening and particularly the links at the bottom of that page.
