Sorry if this question should be better showing up at the flexcomponent group. I didn't have any luck there so far;)
Suppose I am motivated enough to roll up my sleeves to do something like what McCune is doing here at tileUI.com: http://www.youtube.com/watch?v=T0N7tgF7OOM Just for the drag part to get started, am I better off implementing the darg-drop framework that Flex provide or should I start from the more basic mouseUp/mouseDown? I guess this question is for every Flex guru besides Doug;) I appreciate it.
