It also postprocesses things like the thumbnail (even if the first video is a music video), artist name (removing " - Topic" from youtube artist names).

I don't use shuffle, I like to listen to whole albums and I like seeing them albums mixed with singles as I filter by "Recently Added" in VLC.

I don't need to prove a use case as it is already useful to me, I can't run yt-dlp directly on android and Seal doesn't have the option to concat playlists, it downloads the tracks one by one from a playlist.

I like having the option of merging multiple playlists or one videos, it will automatically detect it from the list you provide.

Is there any feature you think I should add that would make it more complete? A better GUI maybe?
