User Group hidden discussion in a thread or attached to a post.
Moderating a huge set of user threads and posts with multiple administrators requires all moderators/admins to read every thread and post. If there was side thread viewable by admins that could remain hidden from the typical users where comments could be made to say "give this user till he gets 10 kudos for this post" or "this issue is moved to an offline discussion board till resolved in say slack channel # blah blah. Hold off response till Admin X responds here." Marking an issue resolved is not all inclusive. Redundant reading of threads and posts costs many companies and users tons of wasted time. A plug-in to enable this may exist as it seems like a no brainer, but I could not find it.
