#33 Be able to have callbacks associated with nodes and edges
It would be very useful to be able to attach callbacks, or to even to just get notification about nodes/edges clicked on, to interact with displayed graph. These could be used to open up additional detail panels, or to use the display as a frontend to interact with a background process. Is there any of doing this?

It would be possible to implement a callback mechanism that triggers callback methods whenever a shape or arc gets selected by a mouse click. The problem is that through the standard/SVG pipeline, ZGRViewer does not know anything about the graph structure. So the callbacks could just tell you that an ellipse, or a polygon, or a curve was clicked, but it would not be able to tell you that it is an edge or node that has a given ID or label.
This issue would be solved by using the augmented DOT pipeline ; unfortunately this pipeline is not fully working (several DOT instructions do not work and there are issues with fonts) and nobody is working on it for now.
