If you want to place the bar in the header (just on top) you can edit in the xml file (before installing it) and instead of navbar (it appear at the end for 2-3 times) with header.
Then you go and place navbar2 hook in the header as the first line. Works like a charm.
You can place also conditional to show some menu's only to registered users:
<if condition="$show['member']">
The link
</if>
I am looking now to add rel no follow to all links that dont require google to search ( I guess it should be there).
Thank you for the mod
