This is another example of a super simple Support class. I'm fairly worried about how confusing the end result of the approach will be. When it was in one huge file, you could at least search for the eventListener that was added to the play button.

If you're searching for `playPauseButton`, you'll easy find this code just like you would have found it in a monolithic source file. But at least here the code related to the behaviour of the play/pause button is clearly contained.
