Media List
----------
 * top shows "<Back", $CURRENT_SECTION [and filter field - later]
 * all sections should start with "All songs"
 * all sections should contain "Shuffle songs"
 * root sections: Songs, Artist, Albums, Genres
 * filter limits the current section and thus creates a dynamic playlist


Library (all from "more")
-------------------------
 * manager: allows add/remove directories
 * rescan: allows rescan media immediately
 * stop-scan: while scanning, allows cancel the process


More
----
 * Preferences:
   * choose media backend (xine, gstreamer)
 * Bookmarks? (show list of songs with bookmarked positions)


Misc
----
 * single instance using dbus
 * export mpris control interface (mini mode could be e17 control using it)
 * support for e_notify (libnotify)
 * read cover from id3? requires id3 image loader in evas
 * fetch covers from webservices (amazon, last.fm)
 * fetch lyrics from webservices (maybe use webkit)
 * fetch track/artist/album info from webservices (wikipedia? uses webkit)
 * audio bookmarks
