Thanls for the reply.
But I am agraid that the term chart in my suggestion was misleading. I ment flow chart. So my point is related to navigation through the list view versus navigation through the graphical flowchart.

Yes, this would be a great enhancement.

Sometimes the list view is more useful than the chart view, especially on the iPhone. While starting to navigate from one subject to another, the list view switch back to chart view. This should be an optional behavior, ot vice versa.

I agree fully with Larry. An import from and export to OPML and XML would be a good start. This program has huge potential. Looking forward.
