* Delay all other rptp commands when the spool is being updated.  Currently,
  the jukebox will crash if, for example, you choose "Get server list" when
  the spool is being updated.  A new RPTP command should only be sent if
  "rptp_mode" is equal to "MODE_IDLE".  This is the most annoying known bug.

* Keep the current selection in the spool list.  Each time the spool is
  updated, the current selection is lost.  This is a real nuisance, as the
  spool is updated every second...

* Fix the bug that smashes the default file name in the "Load list ..." and
  "Save list ..." menus entries.

* Implement "Sort by size", "Shuffle" and "Build list from directory".  These
  options have been temporarily removed from the menus.

* Use the "Multilist" widget (from the Free Widget Foundation) instead of the
  normal "List" widget.  Do something with double-clicks in the lists.

* Add some comments in the source files.

* Remove the debug messages.  Use popups for fatal error messages.

* Add a status bar, where all useful messages will be displayed.

* Add an "options" menu in the jukebox panel, with the following entries :
  "Set volume", "Set priority", "Set delay betweens sounds" ...

* Add an "options" menu in the spool panel, with the following entries :
  "Toggle spool auto-update", "Set refresh rate", "Toggle host display",
  "Show access permissions".

* Add more comments in the source files.

* Add some command-line options (and the corresponding X resources).

* Change the colors.
