The system Moderator group is still being worked on and finalized, as it functions in a global context from what I understand. Category moderators allow for fine-tuning of access. In the mean time however, your moderators can be added to all categories with just a few clicks if needed.
@wrath625, not presently, and I'm running from master. One of the team members may be able to provide some update on the planned implementation. I took a quick look at the milestones and did not see this listed. Most likely the team will need to complete some other permission system alterations around the same time as well.
I really wanted to avoid what I (personally) felt was an overabundance of options for permissions. For example, look at Drupal's:
So we aimed to make it simple to use, though this often does come at the expense of power. We did revamp the permissions/privileges system a lot recently, so we're hoping the frontend will follow as well.
