For the graph, its potential is in knowledge discovery and it would be great to support this better. A couple of suggestions/ideas. 1. Might it be possible to show peeked previewed on mouse-over the graph notes? Perhaps as an option to toggle on/off? 2. Might it be possible to show some additional information under the nodes, again optionally. Say a brief description and/or a thumbnail image? These could be the top of the note or some specific parts, indicated by block anchors, for example.
