Transparent header – next section area (white space with arrow)

Hi,

First off, great new update with transparent header. I have missed this option :)
In your own example with transparent header there is a little white space with a ‘arrow-down’ to next section in the buttom of the slide: http://kriesi.at/themes/enfold/transparent-header/

Is this a public feature/setting? if yes, where do I select to have this?

Thanks in advance.
