Did now :) (I think I did in the past). However, I need to place it 
after a preceding sibling, not simply append it. I am using it for an 
HTML UI were users can reorder folder/page like elements in the tree.

Or are you just saying that I should be using detach() (don't know why I 
am not using it...)?

thanks,
-Rob
