Has anyone thought about creating a clone of this Prototype component (which was itself a clone of a MooTools version). Would be _really_ nice for the Ext community! I started to take a stab at it, but it seems like a lot of work (and my prototype skills are sorely lacking).

Alternatively, if someone knows of an effort like this already underway, please let me know.
