Manipulating multiple playlists

[dtinhvo]

My workflow (I come from MediaMonkey) involves moving tracks between multiple playlists quickly in a session. Also I want to manipulate (unpin, delete,...) multiple playlists at once. This leads to some questions of Tauon's functionalities:

• Can I select multiple playlists at once, for example to unpin and export them all? If not , a CLI command to manipulate the state of the player would be helpful.
• Can I make playlists nested? This would mean something like Rock -> AltRock | MathRock, and Rock has all the tracks of its children playlists. Optionally, when searching for playlists, the parent playlist can be treated as a prefix in the query results.
