I have a suggestion regarding the navigation in the left frame. What do you think if we would display a little icon next to each node to indicate the content type of the link? It is much more usable that way since the user is informed about the what is coming next.
Existing meta-data to a node might also prove useful. If for instance we have to deal with a simple html page but we know that the relevant part of it is an embedded object like an applet, flash or movie.
What do you think?
Greetings,
