I just installed BabyIdeAllInOne in my working trunk image. I have only
just started to look at it, but I have to say right away that the browser
is really interesting. It has a context view that provides an conventional
browser view, and you can switch to an interaction view that shows a graphical
interaction diagram. The objects in the diagram are live, and selecting one
displays its methods and their implementation.
