While building PDF Fan, I had to separate two things people often mean by “clean up a PDF.” Removing metadata clears fields like the document title and author. It leaves visible text on the pages intact. To test the difference, make a sample PDF with the same phrase in its title and on page 1, then check both after cleanup. I built a browser-based tool for this so the original file stays on your device. https://pdf.fan/
What should happen when a viewer presses C?
I build subtitle.im, a Chrome extension for YouTube transcripts and caption controls. What should happen when a viewer presses C halfway through a video?
The viewer’s choice wins for the rest of that viewing. It stops automatic caption changes. Saving a rule for the video or channel takes a separate action, so turning captions on to catch one line won’t affect the next visit.
If your extension automates a setting the site already controls, test the handover. Set an automatic preference, use the site’s own control, then reload. The manual choice should take effect immediately and the saved preference should apply when you come back.
This guide shows how we explain the three caption modes and the manual override to viewers. https://subtitle.im/blog/youtube-caption-control-modes/
