Okay, I've had a hack at it now. I think that I have gotten them working in a basic form. I have not even looked into changing how the dependency arrows are drawn. The attached JPG shows an example. The patch shows, well, my changes in the libplanner directory. It would be good if somebody can let me know if I have implemented what is intended. I hope that in any case it is better than them not being implemented at all. I am thinking that I should farm that switch out to another function, I usually program with tabs set to 4 and had trouble coming to terms with the lack of column real-estate. Also, this is the first time I have sumbitted anything to an open-source project. Let me know if I did anything stupid, wrong, un-ethical. Thanks, Corey b.t.w. Malcolm, thanks for the heads up.
