ah, well that's just never going to happen. everybody fancies
themselves a GUI designer (or GUI re-designer), and very few
are working in environments where meddling with a functional
GUI is considered a sin (these environments do exist, some parts
of my day job have such constraints; they are taken very
seriously and with good reason.)
