Reword some of the UI text
In the frontend, there are a few pieces of text that should probably be cleaned up a bit.
For instance, when you select a domain, there's an option that says "Moderation settings" with a subheading of "Approve and delete comments", but that's not what that pane actually does. I'd suggest "Manage moderators" and "Manage elevated permissions" or something like that.
More generally, I'd suggest changing up the text so that it describes what a user can do on each of the pages. So instead of "General settings", maybe "Configure domain". Instead of "Moderation settings", "Manage moderators". "Statistics" -> "View activity". Things like that. Drupal did that and the admin UI got a lot more intuitive. This UI is already pretty intuitive of course, but it's probably worth picking a style and sticking with it.
