Records the parts of a video that were actually played and paints them on the progress bar, so scattered sections of long videos and streams stay visible across sessions. Playback is merged into ranges per video; seeking, ads, a paused player and streams without a known duration add nothing. The ranges of the 200 most recently watched videos are kept in extension storage. The ranges are drawn per chapter below YouTube's own bars, which leaves the played and the buffered progress untouched. The feature is off by default and switchable under Appearance > Player. Closes code-charity#4261
The player element is registered before its video element exists, so initialising from that point could miss the first video of a page load. The interval now starts right away and attaches the tracking once the video shows up.

Hey @Stiven-Gjekaj, Thanks for the PR. But it would be good if you could attach screenshots so that they can help in the review process, and it can be faster

Thanks @rajanarahul93 Will do. I'm away on vacation right now, so I'll add screenshots as soon as I'm back home. |
