While playing with RTMultiLine I thought that it would be nice to have option for RTDraggable elements to snap to a grid / move only by fixed increments - for example the position could only be divisible by 10 (grid size would be 10), so dragging from 20@10 to 26@4 would jump to 30@0. Is something like this possible with current implementation? The second question is: is it possible for element to subscribe for position updates of another element? (I.e. element A watches for movement of element B and moves accordingly). I know I could add both of them to a composite shape or RTGroup (RTDraggable>>groupToDrag:), however I would prefer something more loosely coupled. In RTDraggable>>initializeElement: i found " element when: TRMouseDragging do: [ :e | e element translateBy: e step. e signalUpdate ]" however it is commented out so perhaps there some other way?
