Preview of Notes
Sometimes I end up with too many notes for nodes in my brains. I would like to be able to see the first few note lines by rolling my cursor over a node. This is similar to the way I can read the description of a link type when I roll my cursor over a link. I find it less useful to traverse a brain if I have to keep looking at the notes at the bottom of the screen.
Other related ideas:
1) Maybe the notes section should have a 200? character header to display the very important information.
2) Maybe only top level notes (via numbering) would be shown
3) Maybe a few sentences could be highlighted with a special color and these show up
