Local logging of playlist (arl use case)

[bachig26]

Since using ARL changes the saved playlist when it's updated.

I hope to see an option save the information like url or some kind to fetch the playlist by saving/updating to local disk in form of text file or json.

In layman terms, save a playlist as a simple txt/json file, then whenever the arl is changed, these saved local file can be fetched right after arl login to update to the playlist section.
