Stefan (I hope you're listening in!)
Brendan and I have been trading messages about this off-list, and came to
the same conclusion:
"Please roll back the code to the old sortables & draggables methods"
Although the methods you added to insert draggables into any sortables is
neat, it lacks the powerful callback abilities that the original
drag/drop/sort functions had. And since it would be possible to replicate
the draggable>sortable functions using those original callback methods, it
seems to make sense to go back.
Please feel free to contact me directly if you'd like to disucss off-list.
