Hello, I was a user of this particular script and I've found some issues with it. it is the fact that the feature for sorting the playlist by the length of video gives me an error message "sort undefined" on the playlist so i was wondering if this would be resolved? please fix issue when you have the chance.

Thank you for your services.

Oh! This should be a problem of symbol encoding judgment. I'll try changing to some common symbols.

If you found this issue when switch to the playlist in Youtube, that can't fix.
Because this script take playlist from cached variable announced by Youtube.
Only there can get attributes that Video ID specific to the playlist.

A easy way is refresh the page.

The script has this restriction because I publish is based on the fact that I don't need to verify YouTube API v3 through a self-built server to perform related operations,and YouTube API v3 not supported Watch Later Playlist yet.
All operation permissions are derived from people current page, and I am not interested in other people's data.
