I had a couple pieces of feedback from a couple of our users that were using this:
Thank you for the comments. The early access build of Creo 184.108.40.206 still has some more work to do with undo/redo within the Live Simulation tab, so we are aware of that not functioning as it should. It is currently being addressed. Also, the selections while inside of Live Simulation tab are currently limited in the early access...so pattern member selection doesn't work like Creo users are accustomed to. This is also being addressed for production.
The locking of the legend scale is a good idea. We have plans to enhance the legend feature in the near future.
