Gary thanks for the infos, I learnt really a lot in this thread. Inspite of the limitations itself in flash, and that it seems becoming less used on web pages, sure are great possibilites in animations.
For example that inspires me in Xara way that on the first frame all the objects can be collected on the pasteboard, which will appear in the whole animation. After simply copying that start frame, the elements are always immediately there for the next frame and any of them can be pulled in and thats all. By this really fast can produce something.
