In order to verify if the MultiJob is configured properly it would be very helpfull if the overview of the Multijob would show:
[on Phase level]
Text or icon for the value of "Continuation condition to next phase when jobs' statuses are:"
!F : Stable or not Stable, but not Failed
[on Job level:
Text or icon for the value of "Abort all other job"
Text or icon for the value of "Kill the phase on"
