It's great that you can get from the "edit library" screen into a rule/element to compare revisions. However, it is frustrating that when you close the rule/element you lose the context and get kicked out to the element/rules list rather than back to the edit library page.
How it currently works:
Edit Library > view rule > compare revision > *close* compare revision > *close* rule > rule list page 😞
How it should work:
Edit Library > view rule > compare revision > *close* compare revision > *close* rule > Edit Library 🙂
Please can you consider changing the work flow to remember the context in which the rule was accessed so you are returned to the appropriate place? - when looking at a lot of rules this would really make a difference!
