If I may add someting to the wishlist:
It is desirable to have something like the control bar with slider for videos also for sound.
For example is a pano comes with a longer narrative, for example to describe the content f the pano, there is yet no possibility to move through a timeline or even see how long the total sound will be
The onyl workaround so far would be to use a video without a visible image, but converting a sound into video, altering the plugin, adding a slider, etc. is a bit clumsy
And of course this should work on all platforms.
Thank you!
