Sortables and their extension to Trees are nice, as long as you don't
need something special. In my experience it can be extremly difficult
to use them in more complicated settings than the examples provided in
Seaside and the script.aculo.us test distribution.

It is certinly simpler to write your own JavaScript handlers using
bare Draggable and Droppable prototypes than trying to customize
