Under an Extension's Right tab, I do like that I can allow an extension access to the Server Management. However, I think this part needs to be improved as the System Managements individual roles needs more granularity. Such as, just simply enabling what tabs or sections the extension has access to, instead of "General System Administration", which enables the extension too much access and I can't seem to restrict the view on specific sections that is customizable. I think it was be very helpful to select or deselect check boxes of each section like Phones, Contacts, Inbound Rules, Recording, Settings, and Call Reports etc. Especially under Settings, remove access from modifying server settings(each blue button). I had an end user accidentally modifying the Email settings, which broke SMTP.
