It seems that the Dependency Graph View plugin is much more than advertised. In addition to viewing dependencies, it allows creating them.
Am I the first to encounter this new, um, feature? I played around with the endpoints in the new Javascript graph view, making new connections and seeing what capabilities jsplumb gives. If I'm not mistaken, the new connections I created were translated to build triggers and duplications of existing dependencies. I think it would be best to disable these effects. In any case, a word of warning to users of this plugin: don't modify the graph! - David
