Hi, Gene, As an X-Plane user myself going on 12 years I can certainly understand how things have just always "worked." Part of that was the simplicity level for which X-Plane offered to artists. Until the SDK came out we did not even have the ability to do things like reverse thrust animations. As time goes on and the market demands it, things like you speak of will go further and further into the realm of departing X-Plane's internal, default capabilities and more features like you speak of will break in replay mode. The only real solution here is for Austin to do a complete re-write, but knowing him as well as I do, I am quite certain this would and is not anywhere near the top of his bucket list. Not having reverse thrust animations (or flaps should it end up that way someday) show up in replay mode is not a bad compromise in my opinion when it comes to functionality during live flight. So long as we are able to push the bounds of X-Plane into a new era, I think the replay mode shouldn't be such a drawback. That said, I do realize I am one man, and this is one man's opinion. In a perfect world we would have both, but we're teeter tottering between leveraging the SDK and pushing the bounds for exceptional add-ons, or keeping thing relatively status quo just for the sake of replaying a landing and seeing an animation "go." Given the options, I'm quite confident we've made the right decision to continue to push the envelope further than what X-Plane's default engine provides, and I dearly hope other developers and distributors do the same!
