Hey Editors and Adobe Officials!
I'm a video editor on Premiere Pro & I work a lot with captions, I add captions to sometimes 15-20 min videos, and my clients like the captions done very neatly and properly, I have to thoroughly check all the captions and change their duration sometimes, for example to split sentences if the speaker is taking pauses, or adjust them smoothly to match a new camera angle by delaying changes until just before the angle shifts, and much more.
I use ripple trim (Q and W keys), and also Extend edit to playhead (Shift+Q and Shift+W). They both are extremely useful and efficient for my workflow but they do not work in the captions track even after ensuring the caption track is targeted. Ripple trim works on caption track but NOT the "Extend edit to playhead". Sometimes, the start of the caption and speaker are not perfectly synced, and in that case I need to use this feature.
I'm not sure if this is a bug, or an un-added feature. Please give your feedback if you face similar situtation and I would be very thankful for this to be fixed, waiting for an official to reply and proceed with this. If you have similar issues, please upvote so we can get this feature added/fixed in the next update. Thanks.
