To me, reveal hidden elements does not really reveal hidden elements. Sure, it reveals elements that were turned of categorically and individually, but what about those that were turned off via Workset or Filter or by other means? Reveal Hidden Elements does not do that.
In addition to the following requests on this forum:

I think Reveal Hidden Elements needs to go further. Perhaps something similar to the Worksharing Display where it color codes elements that are hidden by category, individually, workset, filter, etc.
