Hook on "next slide" event to add custom animations

[bakaburg1]

Hello!

I'd like to add some simple animation, that is showing an element at the presenter's input.

I know you provide -- or layout, but these cannot be used if the element to animate is inside another one.

I think an easy workaround would just be to use some js to change the class of the element, but for this I need to hook on the event triggered when slide change is attempted. What is this event called? where is it attached?

Thanks!
