Free extensions for Joomla!

Hi guys.

I´ve tried to adapt the <ul> generated by html sitemap because my sitemap is too long and cause items to be dificult to localize. I'm thinking in turn the list into a tree menu. In this site I've found a plugin called MooTree, but it doesn't work in Joomla 1.6.

It could be updated and integrated to Xmap as an optional (package), so if someone decides to use it, simply activate it!

What do you guys think?
