Community Settings allow you to create some filters to prevent certain content from even posting on your videos. For example, you can add key words that you would NEVER want to appear - hate speech for one.
Comments section shows Published, Pending (if you set them to be approved) and Marked as Spam which I would recommend you check, most of mine were not spam. There does not appear to be an option to approve multiple comments at the same time so when you scroll over the video name you can go directly to the video to approve it there. The bold comment that moderation and other features coming soon makes me think that this option will be available at some point.
Here is another view of several comments I need to approve.In addition, there is an Insight option that keeps producing a code error so I could not share what it looks like, yet. I will check back till it's live and add the information here.

I will continue to poke around these changed and add anything I discover here. Just wanted to give everyone a heads up on the relocated and barred Inbox.
