Well... yes. I could add "minimum" and "maximum" labels easily enough, 
but I don't see that the number has any inherent meaning to the user. 
What does "4" mean? What does "0" mean when it *doesn't* mean "none"? 
Aren't arbitrary meaningless numbers /also/ bad usability?

So... if the groupbox said "shading" and had "Frames and '3D' lighting 
effects" in a tooltip, would that be okay? I am seriously concerned 
about putting all of it as the group title when it gets translated into, 
say, German (or any language with really long words)...
