Hi there. I know we can lock whole audio and video tracks in a Premiere timeline, which i use a lot. Suggestion --> It'd be even better if we had more accurate control over what was locked in a timeline, instead of only being able to lock entire audio or video tracks. As in, in my timeline, I'd like to be able to click/lasso select single video/audio clips or multiple video/audio clips, anywhere throughout the timeline, and then, JUST LOCK THOSE SPECIFIC SELECTED CLIPS, similar to how I can "enable" or "disable" single clips in Premiere. That way, for safety, I can lock certain portions of my timeline, and keep working on other parts of it, and know with confidence that no matter what I do, the parts of the timeline I locked are safe. Often times, when working on small portion of the timeline, I can accidentally hit a key that causes unintentional and undesirable changes elsewhere in my timeline, that only later do I discover, and then have to go back to archives and try to figure out what happened. Every single editor I've discussed this potential functionality with thinks it would be revolutionary and change the way they edit.
