- * @brief Playlist for Disobedience

*
* The playlists management window contains:
- * - a list of all playlists
+ * - the playlist picker (a list of all playlists) TODO should be a tree!
* - an add button
* - a delete button
- * - a drag+drop capable view of the playlist
- * - a close button
+ * - the playlist editor (a d+d-capable view of the currently picked playlist)
+ * - a close button TODO
+ *
+ * This file also maintains the playlist menu, allowing playlists to be
+ * activated from the main window's menu.
+ *
+ * Internally we maintain the playlist list, which is just the current list of
+ * playlists. Changes to this are reflected in the playlist menu and the
+ * playlist picker.
