Would it be possible to change the function addNavigation() to have these arguments:

$title, $url='', $seoTitle='', $seoTemplate='', $base='public'

Currently, $url does not set that empty string as default, so it always has to be defined, but if you want to create a navigation element that's just text and not a link you always currently have to pass in the empty string, and I usually forget to do that.

Report this to the bug tracker and I'll sort it for next point release (I know it's not a bug).

Thanks, reported :)
