offline mode enhancements

lately I’ve been using the offline mode more frequently (on mac) and i’ve noticed that quite a lot of features are missing. of course i didn't expect the same experience as in the online version (which already is the best music player for mac!), but i guess some things like a simple search function, songs/albums/artists/playlists categories could technically be accessible even without a connection to the server?

currently there’s only the downloads category, the album artworks of the downloaded songs and a shuffle button. would be awesome if a few of the main features were also available in offline mode :)
