Right now, the two name servers from the Options tab are used for the NS record. There's no plan yet to add a function to add additional name servers.
I was actually more interested in, for example, adding the entries for a sub-domain. This would require 2 more options on the records screen (at least, different from ISPConfig 2): An arbitrarily named NS record, and an arbitrarily named A record Eg: In the configuration for example.com, adding sub-domain sub.example.com: sub.example.com NS ns1.sub.example.com ns1.sub.example.com A x.x.x.x Basically, support for "glue" records.
