Would be amazing to have also an event when the elements scoll out of the view.

I would also add a config for percentages in and out of the viewport. For example, I'd like to be notified when a video is 25% into view and 75% out of view to start playing it and stoping it respectively.

Hi all,
we are accepting PRs for this, if you want to add that functionality to the library.
