1) can I add sounds to a timeline?
2) how do I make sprites appear at specific places on the timeline (but not before)? Right now I'm having two keyframes next to each other to instantly tween from opacity 0 to 100, but this is clunky. Can I have a sprite just not appear on the timeline at all until a specific time?
3) is there a way to make conditions based on timelines? (eg. On timeline is playing, or when timeline reaches time X, etc). I guess being able to do this would take care of point #1.
