As it stands we're able to make windows in interfaces transparent, but the same cannot be said for what we put in those windows; particularly grids. Is there any way we could get an option for that? I've heard mixed things about output transparency, and it causing lag, but what about grids?

I'm aware that HUD's are often used for this type of thing, but it seems to me like grids would be easier, and should support this feature. Maybe people wouldn't need to spend so much time designing HUD's if grids were more flexible like this.
