We have thought about this but don't yet have a good solution to importing the data. PDF allows too much so that we would need to include a third party PDF reader which comes with all kinds of headaches for our multi-platform sim. Users would then probably have to save the sequence as a square texture and convert it but that's not an easy plug and play system.
Thanks for thinking about it! I don't mind converting to any image format. And IAC the aerobatic boxes? Have you considered that? Those two things would really be the cat's meow.
