Another thing I find most confusing when viewing orders as Admin> (orders.detail) is that the Comments and Reviews Addon buttons do not show for individual orders!
I need to select "All Stores" to show the Addon and Communication Button.
This is contrary to the fact that the Communication Addon settings are enabled for Orders for the individual store.
Thus I'd expect the addon/Communication Buttons to show regardless of which store is selected, or if All Stores is being viewed.
It seems the architect has used AND logic rather OR.
