Show/hide layers with JavaScript

The functionality of the JavaScript API to change image states has been a very appreciated godsend.

I'm not sure what would be involved, but the ability to show and hide layers with JavaScript seems like the next evolution.

The current workaround is to create a kind of "predicate" boolean in Storyline, changing its value with JavaScript, and then using secondary triggers to respond to that variable's change, showing and hiding according to that variable's value. It works well enough in that there's no real alternative, but JavaScript would allow much more conditional logic to determine which layers are shown and hidden as well as when.
