🛠 Technical Details

Version 6.0 replaced the broken DOM drag-and-drop approach with YouTube's youtubei/v1/browse/edit_playlist API:

• ACTION_MOVE_VIDEO_AFTER — moves videos to their correct positions
• SAPISIDHASH authentication — uses your session cookie to authorize requests
• ytInitialData parsing — extracts setVideoId identifiers from YouTube's page data
• Virtual array tracking — tracks order in memory (DOM doesn't reflect API changes until reload)
