This is exactly what I was looking for! I was going to make a menu that did something similar but your extension made life a lot easier. I was easily able to re-style it as needed. Only thing I can think of to add might be a option in the module to Show or Hide the titles. For example when I used it in order to hide the title "Login" I had to use CSS to display:none all h3 tags.
Excellent work thank you so much!
