Currently maintaining a validation configuration is cumbersome, because each rule has to be selected individually, there is not sufficient filtering/grouping possibilities and it is hard to identify newly released rules or any other change to the rules. The following features would improve user experience:
Possibility to filter by rule category (e.g. "postal code checks", "name checks", "VAT checks"...). The current feature selection is too broad. As a user I want to define, e.g. "missing postal codes are warnings in all countries, except country X, Y and Z where they are errors" and this should be possible to maintain with first selecting all and then adjusting criticallity for the 3 exceptions (also see next point).
Possibility to maintain criticality & exclusion for all rules of a given category (across all countries)
Possibility to filter those rules that have been adjusted + possibility to reset to default
Highlight (flag + first in list) changes / new rules, ideally with a flag on the app (homescreen) aswell
