It's all theme dependent. This is actually based on your idea here. I  
just explicitly names each tab and names the group. That way you can  
color the leading space on one side one color and the other side  
another color.

I think both methods have their place. That's why i think we need  
some sort of injection scheme.
So we can have either method used in any language without  
modification by injecting the scopes into it somehow.
