Unfortunately, it looks like it might not have helped in my case. It appears that it is doing a round trip to the server and back on every open/close of a node. That's exactly what I had to avoid. Our tree has > 1000 elements (and growing) pulled dynamically out of a database. In a multi-user environment we don't want to be hitting the server that hard just for a navigational menu for every click of every user. We serve up the entire tree when the user logs in, and all of the state maintenance is handled client-side in terms of what's been opened, etc... we never go back to the server unless the user has requested a refresh of the tree. I could be wrong in how your module operates, that's just from a 3 minute session with the demo. It's good that you've made this available though, most people will have more reasonably sized and constructed trees than we do and should find that module useful. :-)
-Fran PS - May want to take a look at it on Mozilla. There seemed to be slight table layout issues on my Mozilla 1.0 (yeah, I need to upgrade :-) that caused the graphics to slightly misalign.
