List Rules Violations
In addition to list rules violated, list rules violations in a new dedicated panel. This would be convenient to pinpoint which assembly / which namespace / which class concentrate a lots of violations.
NDepend v2017.1 just released now supports enhanced Issues Management and even Issues-Set querying through C# LINQ
To be specific, it would be very helpful to select a type/method/namespace from the list of assemblies and see violations only pertaining to this selection.
