Advanced Wordpress Menu Manager?

Does there exist some kind of advanced Wordpress menu manager that would allow one to control which menu appears per page or area of a web site? As opposed to the standard menu behavior, which is that all menus appear on all pages?

So far I have not found anything on the subject, except this...

... and this:

It's strange that there is so little available to this end, as it seems that advanced menu functionality could greatly increase the range of a web site without bloating the navigation. I suppose I could try WP Menu Creator, but I'd rather not use a pre-wp3 plugin on my site.
