Ah. I didn’t bother to think about the possibility that a given edit might change some proportional relationship based on timing, etc. However, there are still a lot of edits that don’t affect those relationships, correct?

Hmm, on second thought, I can see that there’s more than meets the eye. I was going to give an example of, say, just nudging a trigger a few pixels one way or the other, or nudging a curve. But they all have absolute X-Y vectors which can be used as the time reference (percentage is not the only choice, is it). Yes, I can see your point :–)
