I suggest the server manager configuration be customized. A lot of features have been suggested but I believe Mitel, through implementation of the cool functionality, may be making the entire administrative function more complicated. As a more experienced user I desire more functionality out of the server manager so I can avoid SSH to a command line. (hassle + security) An option at the top of the list of administrative categories could state basic or advanced. The basic would not deviate from the current configuration (perhaps a bit simpler) and advanced would allow more flexibility in modifying different aspects of the system. (webmin-type - i.e., lots of intricate options advanced users would need) A design committee could decide which functionality is "advanced" perhaps by going through the general users forum. Many do not know how to configure/customize but want a functional server. Later with more experience they start to explore as enterprise needs change or are proposed.
