Thanks, but this is a special section of the panel that only shows
active processes, like the "tray" in Windows.  It does not seem to
allow the normal right-click operations -- if I right click on it, I get
options to remove all the launch buttons but nothing about the
things appearing in this box.

Does anybody know in what *files* this thing is configured, so I
can hack on the configuration?
