Ok, after revisiting this, I guess really what I’m doing is making a feature request to have separate options for each of the display features. From what I can tell, there are comments, participants, simple comment links and complex comment links. Perhaps there are others that I’m missing. In the future, I guess topicmap could be another display feature.
Anyway, right now it appears that complex links and participants just show up when comments are displayed. And simple links are shown when comments are not displayed.
I think in the end what I’ll want is the topicmap (once that’s working well) and the complex comment links. I’m just not sure how to get there without separating out the display options more than they currently are—hence the feature request.
