You mention that importing playlist will be available.............but when??? It is a really important aspect for me and maybe others who have used other programs and have organised their music into playlists. As soon as importing of playlist is enabled then you can willing have my cash!!
Import of playlists is ready ... to be relesed in the next version. The rough estimates of when it will be, is 1 month for some alpha/beta version and 2 months for final release, but it is really just an estimate.
Yes, it is in MM 2.0, it imports automatically all playlists in your collection during scanning of your drives. You can find them in 'Playlists\Imported m3u playlists' node.
If you want open an .m3u playlist later manually, you can 'Add' button of 'Now Playing' window.
