shion Thank you for taking the time to share your input! We have received many other requests from users for folder functionality, and we recognize that this is a high priority issue.
As far as improving the ease of integration with After Effects, I don't think we'll be able to make any major improvements any time soon. It is possible that other improvements, such as adding the folder features, will make it easier to work with AE, but there are no plans to add AE-specific improvements, at least not in the near future. Spine is still an animation tool for games, so improving its integration with game engines is a higher priority. It may be better for you to consider using another tool instead of Spine.
Again, we appreciate you taking the time to let us know what you think. I hope you understand that I was not trying to ignore your opinion, but simply saying that it would be better to find a way to resolve your issue quickly than to make you wait a long time with your expectations.
