Just in case anyone is interested about saving their screen real estate
but keeping their panels, there is a way. It took some experimentation,
but if you make all the icons in your panel smaller (at the moment all
of mine are 16x16, when next you login the panel will be very narrow,
mine at the moment is 20 pixels.
Had some fun with gimp and mogrify and the rox icons to do it, but
results have happened.:)
