Support for exporting entire library
I have never used playlists, only added albums to my Spotify library. I can't export anything with this tool.

Looks like someone made this and contributed the feature, but the project is abandoned...

See also the link in the (currently) last comment to their fork where this is supposedly implemented. This worked for me :)
The project isn't abandoned, just under-loved 😞 . I'm currently looking at ways to be more reactive in future, starting with a triage of existing topics.
This is indeed a subject that has been mentioned several times and strikes me as useful. Let's use this as the master going forward, as it was the first.
