    Why Tree DnD doesn't support COPY or INSERT?

      The default mx:Tree drag-and-drop only supports MOVE. For instance, one can drag an item from Tree A and _move_ to Tree B but can't _add_ that item to Tree B unless you extend mx.controls.Tree, override dragDropHandler() and dragCompleteHandler() and, if lucky, write the logic right to calculate the insertion point and insert into the right spot in the tree data structure, etc. etc.

      Why app developers have to do this just to add items from a tree to another?
