Playlists have always been a pain-point with ytdl-sub. If an author adds new videos to the end of a playlist, as opposed to the front, it breaks ytdl-sub's intuition of incremental scraping by breaking on the first (oldest) video. This update now makes it possible to handle this in the prebuilt TV Show presets:
- Add each URL variable (`url`, `url2`, ...) into the `download` portion of the subscription twice
- First definition is what we all know and use, simply scrapes first-to-last, then downloads last-to-first
- Second definition does the following:
- Check to see if a URL is a YouTube playlist URL, if so...
- Set the field to download, but with modifications to scrape last-to-first, then download first-to-last
- Otherwise...
- Set the field to an empty string, which means ytdl-sub will skip it
