The widget would be a nice (optional) addition. But, the question is 
where would this widget be displayed without wasting large amounts of 
screen space? You probably know that we use khtml to display the 
messages. I don't think it's possible to include an arbitrary widget in 
khtml. One possible solution would be an image with an imagemap. But 
then things like tooltips would of course not be possible. Using 
JavaScript is also no option because this would open a can of worms (at 
least as long as we can't display the message body in an embedded 
sandbox).

Two remarks about the screenshots:
Some of the screenshots show intersecting arcs. But it's always possible 
to draw an intersection-free graph (AFAIU the paper the order of nodes 
is independent of the message date). Also large arcs as the ones in the 
first screenshot should be avoided.

Regards,
Ingo
