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

I like this, I would like to drill down on this subject.

What it is you wish to accomplish with this module?

Looking forward to seeing what @AbsyntH get done there

From 6.6 release notes:
New page, Server certificate shows the self-signed SSL certificate and allows generating a new one, customizing also the alternative names of the server. As a consequence, changing the host name from the Server name page does not generate a new SSL certificate anymore. The same applies to the Organization contacts.
