I would love to see "Animation needs more events" resolved [1]. Maybe following events: started, paused, resumed, cycleStarted, cycleEnded, stopped/ended? These additional life cycle events would allow me to do some things with animations/transitions that I've been struggling to do.
There may even be use cases events for starting, pausing, resuming, cycleStarting, cycleEnding, stopping/ending. [1]: https://bugs.openjdk.java.net/browse/JDK-8092408
