Hi, dear Greensockers!   I wonder if you could help me with a tip concerning this problem:   I have various functions build following this scheme:   function introAnim(){ let tl = new TimelineMax() tl.add(someTween, 0, vars) tl.add(someTween2, 0.2, vars) [...] return tl } function hideIntro(){ // first and foremost this tween has to stop, whatever could still be going on in introAnim - how to??? let tl = new TimelineMax() tl.add(hideTween, 0, vars)
