Suggest to clear metrics that have no occurrences

[fwuensche]

From the image you can see that the latest report happened 3 days ago.

It means that there were no occurrences for the other metrics.

Shouldn't we suggest a quick way to clear the metrics that have no more occurrences, such as adding a small banner with a button to clear them out? 🧹

Given that clearing a metrics is an achievement (in our case, we cleared a metric which took 2 years and many effort !) I would go even further with this ;)
A nice thing would be to have the metrics still accessible for history reason

You could propose a "Completed" section with all completed metrics ( = 0 occurences) and a "Complete" button (don't forget the confetti !)
