Something I've posted about previously, and submitted formal suggestions, a long time ago.
When there are locked events whose relative position to other events would be affected by Ripple, whether Auto or Post, I want Vegas to flag a warning, saying:
"There are locked Events which may be affected by this Ripple - do you want to proceed?"
This surely can't be too difficult - it's something that crops up from time to time - when I've been deleting and shortening events, as you do when fine tuning an edit, then suddenly coming across a locked event, often way down the timeline, which has not been moved by all those Ripples because it is locked, and which now causes lots of confusion.
Please Sony - at the very least, if there's a technical reason why it's not practical - TELL ME!
