* frontend:
- infos about song being played:
  - song attributes (channels, frequency, bitrate);
- ability to modify song attributes (artist, genre, ...);
- make Cynthiune playlist-oriented (document interface?);
- make Cynthiune themeable, if possible by supporting Winamp/XMMS skins;
- the info menu should include a "Check for update..." option;
- add the ability to remove duplicate songs;

* formats:
- MPC bundle
- AAC/MP4 bundle
- A52 bundle
- ability to play HTTP streams;
- compatibility layer with XMMS plugins;

* players:
- implement a real GNUstep output bundle using gnustep_sndd;
- arts output bundle;
- CD writing output bundle;
- this thread thing needs to be optimized;
- implement CD reading, modify the open dialog so that it can read CD tracks;

* playlist:
- write a full-featured playlist manager;
- the PlaylistFile class should handle relative paths;
- sorting should take directories into account to differenciate two different files with the same meta tags.

* translations:
- write translations;

* documentation:
- write a user manual;
- a dev. manual (plugins) ?;

* maybe:
- scripting and/or remote control interface?

* BUGS:
- leaks?;
- drag & dropping folders does not work, things need to be cleaned up and rearranged between PlaylistController and TableViewController;
