21 * @brief Playlist support for Disobedience
23 * The playlists management window contains:
24 * - the playlist picker (a list of all playlists) TODO should be a tree!
27 * - the playlist editor (a d+d-capable view of the currently picked playlist)
28 * - a close button TODO
30 * This file also maintains the playlist menu, allowing playlists to be
31 * activated from the main window's menu.
33 * Internally we maintain the playlist list, which is just the current list of
34 * playlists. Changes to this are reflected in the playlist menu and the
