It's very clear to see there is a ZOS comment on a post with the red [ Z ] icon adjacent to the entry.
What is not so easy is to find the one or more comments within the post when there is a lot of pages to scan.
For what is currently a "hot" topic there may be a large number of pages quickly generated.
Before I go reading too much of the post I would rather see what the ZOS position or response(s) is/are (if the post is tagged with the red [ Z ]).
It's quite feasible to add some marker to the page number to indicate this (even making the specific page numbers "Red" would work).
