The original Playlist Export Tool is no longer maintained by the creator Hector Avila. V2 contains some new features, and a new maintainer, Wilco.
This extensions allows the creation of m3u or pls files. These can be absolute or relative links, and so can be copied to other computers (and will work windows<->linux/osx).

Updated to work with 1.10.1
