ResophNotes sports Internal Links. Enclosing any word or words with square brackets, creates a link to a topic with that name. If the topic exists, it links to the existing topic. If the topic does not exist, you are asked whether you want to create it. Clicking O.K. does create it. It's like a very simple wiki, though deleting a just created topic does not remove the link (nor does it change it back to look like a potential link). But it's obviously not meant to reproduce all wiki capabilities. Notetab, for instance, behaves very much like this.
The links are case sensitive, so [New topic], [new Topic], and [new topic] all create different topics. (Don't know whether that is good.)
Still, I would say that this feature puts ResophNotes heads and shoulders above Notational Velocity and Nottingham. It's an example of a PC applications that has become in a short much better than anything available for the Mac! I'd just wish someone would do this for a simple Outliner.
