Missing menu in theme options

Hi,

I wanted to add a pattern to the header and found out that there is a missing option in the theme options panel.

Its in the patterns menu below the header pattern:
IMPORTANT:
The Header background color opacity must not be set to “100”. See setting.

Another question on that topic, is there an option to add a semitransparent pattern to the row backgrounds? This is very useful to add sharpness to it etc..

Thanks!!
