I’m seeing artifacts related to drop animation using the wrong rect (cell index off by one) in some edge cases in SpringBoard and zapping the cells prematurely, triggering a recreation process; those issues will be resolved later.
AQGridView needs a canonical cell dragging demo and the SpringBoard demo does not work properly after the ARC conversion.
