the administration menu/control center needs an option called disks, drives, harddrives or storage. this should give you access to boot menu, partitions, filesystems, swap, mount options, encryption and options for secure deleting / cleanup.

When using a custom theme and running an administrative program, like Update Manager or Synaptic, the interface is very ugly, I think it's the default theme of Gnome. This is because the root account doesn't have the custom theme. Why not store the themes in a central location, like /usr/share/themes? This can be done easily and with making symlinks, no changes in the software are needed for this. So please do this, it's annoying and ugly.

This is what I mean:
