In our build graph, some builds trigger the same job multiple times with different parameter(s) values. Currently, such child jobs look identical on the graph. It would be very useful to have the "Toggle Parameters" button which would render values of parameters that were used when triggering the child job, if any.

In some cases, I guess, the amount of info could be overwhelming, so perhaps some kind of parameter names whitelist/blacklist could be also useful (either global or per-job).

As an alternative approach to consider (instead of toggling) a mouse hover-over tooltip could be shown instead.
