I actually think this is a great idea! This must be a MAJOR UX no-no when
it comes to users watching content or working with content. My use case is
looking at a recipe and having two hands covered in cake mix and then the
device screen going off and I have no idea what to do next because I canšt
see the recipe anymore! Further than this, some people might watch videos
and like to read comments (for example) at the same time.

Does anyone else think that this kind of API would be useful?

Thanks! Natasha
