YouTube Playlist Date Sorter 제작자: harness

This extension is built as a plain Manifest V3 WebExtension without bundlers, minifiers, transpilers, or generated JavaScript.

It runs content scripts on YouTube pages and shows a bottom-right panel only when the current page has a playlist ID. The extension reads the visible playlist DOM to collect video IDs, fetches each video page HTML, extracts publish dates from metadata such as publishDate/datePublished, then sorts the visible playlist items in the browser DOM.

The extension does not use the YouTube Data API, does not require an API key, and does not modify the playlist on YouTube. It only changes the visible order in the current browser page and builds the next video URL for navigation.

User settings and per-playlist sort results are stored locally with browser storage. No user data is transmitted to an external server.
