I'd find it useful to have an optional "slot" column on the task list, to show the slot in which a WU is running.
Bonus: Click on the slot number to open an editor on the stderr file on that slot.
Could also add a "bunkering" option so that selected WUs could be automatically suspended when they reach xx% complete until xx time.
Could license this option for revenue...
Isn't this a BoincTasks request.
You can add a rule to suspend tasks when they reach more than % or stall.
