For anyone following along, it was quite easy to do actually.
 
First I added the `onDragStart` event to the draggable which just called `tl.pause()` to stop autoplaying when we start dragging.
Then I hooked into `onThrowComplete` which was currently calling `syncIndex()`. I created my own callback (that first calls syncIndex), then:
 
gsap.set(tl, { timeScale: 0 }) tl.play() gsap.to(tl, { timeScale: 1, ease: 'power2.in', duration: 2 })
