Nestle a playlist within a playlist
I have mentioned this before but didn't explain it very well. I would love to have the ability to add a playlist into a playlist.
Imagine you have 1 topic, which is split into four subtopics. In turn, each of the subtopics is divided into four categories. At present I would have to build one playlist of 16 videos.
It would be better if I could have 1 playlist called Topic Name. Inside this playlist have four playlists called the Subtopic Names and inside each of them have the four categories
Visually less daunting, creatively more appealing and logical improvement
