The whiteboard itself is just a list of json objects with a pretty simple format explaining their properties (color, text, location, etc.). It would be interesting to make this visible as a library to the python (etc.) code that you run in the whiteboard. That would make it possible to create arbitrary whiteboard elements -- lines, notes, more code, pages, icons, text, etc., -- dynamically, as the result of running code. Since the whiteboard also supports ipywidgets, this could be an interesting and compelling "canvas" for certain types of applications.

The api should also include ability to move focus to any element of the whiteboard (defined by its hash).
