Looks like I need to just create this myself. I need to do this because our settings area is getting cluttered with internal spam/virus/whitelist/blacklist etc settings, and I want to create 1 tab that holds them all.
Would it be useful if I made a plugin that does nothing but create a new tab, and allows other plugins to register on that tab? Where the tab name and hook name would be configurable? Not sure if other people would have a use for this.
Regards,
Cor
