Hi, I've been playing around with the tree functionality as well. Looking at the code, you'll notice that the reorder method calls itself recursively. If you want to reorder the entire tree, simply pass no arguments... e.g.
$this->reorder(); Overall, I'm pretty impressed so far with how easy the tree methods make it to deal with the adjacency list hierarchy model. I've had to code this kind of stuff from the ground up in SQL Server, and it was a major PITA.
