I'm sure for some of you it's not new, but lets describe it for the rest of us :).
If you look at the source code of yours or ours page and search
<div id="navigation">
(ctrl f for the search box) you will see a list (ul) of links (li) in this case. That is what appearantly, the house menu spits.
Now you will see that each item gets a different id number .
The good news is that Current page gets:
id="HouseMenuNavCurrentItem"
That is more than we need!
Simply add to your skin.css:
#HouseMenuNavCurrentItem{} ///** styling the box around the link **///
And start filling it out!
good luck!
You can find the menu here:
