Seems like the Radiator plugin treats unstable & stable jobs as correct ones, and only failed ones as problematic.
I really like the idea of displaying the failed one bigger than OK (when showing also stable, I mean), but I guess this would be even better to display unstable ones with a bigger size than stable ones.
I'm attaching a screenshot to clarify.
If you don't think this idea is stupid/useless, if you want we could even have a look at the code and propose a PR.
Thanks for the feedback.
