I feel that the iconbox is another floating panel like the original panel, and
most people (that use it) put the iconbox on the same edge of the screen as the
panel. The iconbox should either mimic the "always on top" nature of the panel,
or have its own setting to do so. It seems like a bug when you have them next to
each other, both looking and somewhat acting like a panel, yet if you maximize a
window to cover them, the panel is incapable of being behind the maximized window.
