I would like to see a function to nest playlists within collections. I see this as very useful for something like making a specific order of items airing in order, but shuffling a list of those. For example, shows that aired two independent episodes as one item, especially when those episodes weren't a predictable length. CN, for example, would air two individual episodes as 1 30 minute episode, with an intro and credits sequence book ending them, and commercials in between. These episodes are split for streaming purposes, but in a live tv scenerio, they are supposed to air together. Some shows use a simple 10-11 minute block, some used 3 7 minute blocks, and many often mixed the two, or would air "specials" that lasted the full 22 minutes. I could make a playlist group for the show, episode 1 being a playlist of the first two episodes joined together.
