ability to add/move things to sublists of the navigation bar

[anonymous]

Hi, it would be nice if you could add stuff to sublists of the navigation bar. that means, what currently looks like:

<ul>
<li>foo</li>
<li>bar</li>
<li>foobar</li>
</ul>

could then look like

<ul>
<li>foo</li>
<li>subfoos</li>
    <ul>
    <li>bar</li>
    <li>foobar</li>
    </ul>
</ul>

This could be handy to integrate into site navigation bars that use such schemes for the current point, so that under a bugtrack point the whole trac points could be

additionally it seems to me that this plugin has similar abilites as NavAdd so maybe they should be merged?
