20/** @file disobedience/playlists.c
b5e60f0d 21 * @brief Playlist support for Disobedience
fc36ecb7 22 *
f0bd437a 23 * The playlists management window contains:
b5e60f0d 24 * - the playlist picker (a list of all playlists) TODO should be a tree!
f0bd437a
RK
25 * - an add button
26 * - a delete button
7fe2807d 27 * - the playlist editor (a d+d-capable view of the currently picked playlist)
b5e60f0d
RK
28 * - a close button TODO
29 *
30 * This file also maintains the playlist menu, allowing playlists to be
31 * activated from the main window's menu.
32 *
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
35 * playlist picker.
