What is the most awesome module/feature for NethServer, that does not yet exist?

We discussed about a page for managing simple RAID arrays.
The page should allow something like:

  • find and replace faulty disks
  • create new arrays (raid 1 or 5) where data can be stored

Under the hood the implementation should be fairly simple (just few bash scripts?), but I’m a little concerned about the GUI design: to make it simple, we should probably lose some flexibility.
