It took me like 5 minutes to come up with a somewhat concise subject title! I hate when that happens.
Anyway, here's the deal. Say I have 4, 5 or 6 video tracks. I have four clips on track 3, for example. I want to tweak the exposure on all of the clips. I go to the 4th clip, make my tweak, then move the timeline cursor to the third clip so I can see what I'm doing to that clip.
But PPro defaults to the clip on track 1, below the clip I want to work on. It's very annoying. I'll make a change, then realize the change was applied to track 1. I have to undo it, then click on the clip in track 4 and apply the change again.
