Matija -- thanks for this feedback. It is a good suggestion. I will explore to see if we have a setting we can adjust or widget we can use that might help improve this information. If not, then I can see if this is scheduled for an upcoming release.
Matija - Actually I just realized this information is available. When you are in any community (or sometimes called a 'space') select Content near the top of the page for that community, filter by the content type you are interested in (in the pictured example I have selected Discussions), then look for the Replies icon and it will indicate the # of replies for any pieces of content. Hope this helps. Let me know if any other questions. Appreciate your involvement in the Mentor Communities.
