Hey, i'm not sure how much control you could allow us to have in the chatroom, but having icons in the chatroom and the private chats would be great also a delete messages and room monitoring like "kick, ban, mute, give mod" i'm not meaning in the admin CP, because logging into the admin CP to remove a bad user would be a pain.
Adding a icon beside names like 3DCity is currently with a VIP or STAFF image would be cool.

Just overall more features that don't allow moderators to be logged into the admin cp to take action against bad users. In all the templates and devices.
With all these features plus the ghost mode to hide staffs profiles, would make things more smooth and secure.
