A dashboard showing not acknowledged errors would help us to identify problematic bundles or workstations.
Compare the today "Message summary" on the "Home" page of ZCC.
Here you can see how many bundles/workstations have critical or warning status.
If you click one of the countings you see the bundles/workstations affected.
But e. g. you don't see which bundle has one error and which bundle has many errors.
Although it's not possible to make a correlation between number of errors and number of installations. (A software 100 times installed with 10 errors is more buggy than a a software 1000 times installed with 10 errors)
