I believe a web GUI menu for disk management would be a great feature to have. It pains me to say it but look how easy it is to manage disks and partitions on any M$ server or client OS including SBS. The same can be said for GUI driven Linux systems.
I understand NS needs to stay a focused product which is slimlined and best of breed.
Taking what can be a daunting task that can kill your whole server and wrap it with a clear,easy to use GUI shows great product maturity.
Having features that no other distro in this market space has is pioneering, innovation and a massive value add. Something others distros will either follow, or fall behind.
I have every faith in the NS team getting the balance right between ease of use and the warnings needed to help the admin make an informed decision when managing disks
