I do not really see a reason to not have this by default, especially given the name "...useful..." :). I would rather want to have a setter to disable this, because this is a more rare case.
It depends I guess. Is it useful to have draggable nodes in a system complexity ? In a UML? Is it useful to have popupText in a UML diagram?

Hi All,
Doru emitted a request on Mondrian. I added the class MOFigureSelection to capture when a node is selected. Example in: MOViewRendererTest>>testFigureSelection
| view node1 announcer | view := MOViewRenderer new. view setUsefulHandlersForNodes. announcer := view interaction. view nodes: (1 to: 20).
node1 := view nodeForDomainValue: 1. self deny: (node1 isSelected). announcer announce: (MOFigureSelection event: nil on: node1). self assert: (node1 isSelected).
Note that the message setUsefulHandlersForNodes should be sent to the view. It is automatically sent within an easel. (maybe this is a point we could discuss).
