You should change your function to this:
> tree.getRootNode().cascade(function(node){
> if (!node.childNodes || node.childNodes.length==0) {
> node.remove();

That would surely remove the leaf nodes as well as empty group nodes?
The trick is recognize that the node is a group node rather than a layer
leaf node.
I never thought of a delay. on remove. Will experiment.
