We have a Test Protool document. That contains Test nodes and those Test nodes point to different Test Step items.
When doing a document difference, the redlines do not make it apparent if changes where made to the Test Steps.
It is reasonable to expect if the steps to perform a Test have changed, that Test will be flagged in the redline view.
I understand that this can be accomplished by creating a custom report, but it seems like a very common use-case for people that rely on PTC Integrity to perform document reviews (and they want to focus their reviews on the items that have changed).
