ETA on Animation - individual frame control per layer

Hi, just asking if there are any updates for the release of the expanded animation layers/timeline as requested here? Animation - individual frame control per layer?

It’s been nearly 8 years since Jmation first requested the feature, and since then it has become one of the top topics on this forum.

I understand these things take time so I hope this post doesn’t come across as ungrateful or whiny. Thanks for the great program!
