and drop

NIce to see such quick action, Doru!
The interface for dropping might become a bit more complex. Let's consider
a tree view. The drop can be either on an element of the tree (supported),
or in the free area below it. But it can also be between elements (to add
at a specific position in the tree) or even at a certain level of the tree
(to add as a child)
