The shiftChildren looks like a nice technique (thanks), though in this case I'd like to shift them dynamically without changing subsequent tweens.
My current thought is to create an array of tweens, each of which is then inserted to the timeline. If I then update the start time of any one of these tweens using the startTime() method, would this automatically update its starting time in the timeline, or would I have to manually remove it from the timeline and reinsert it at the new starting position?
Thanks.
