Estimation error is one of the ideas. The other ones I have in mind is: (i)
accumulative time or percentage per node and (ii) color node that has
estimation off (if the terminal support colors). Of course, those features
should be enabled using some explain options like ACCUMULATIVE and COLOR.
Another explain tool that has a similar approach is http://explain.depesz.com/ .
