1 - Unfortunately, bug #6 in my bug report from the last beta has not been fixed:
Specifically, this one:
If multiple clips are moved beyond the left of the timeline then it will cause the clips to be altered in the timeline. Here’s a demo of that.
2 - Have 2 clips on V2 and 1 clip in between them on V1. Multiselect all three then ripple delete them. The 3rd clip (2nd clip on V2) won’t be deleted. Demo.
