TBH, I have never developed with python, but confconsoly.py seems as hard as any other uncommented script to understand :-P.

For example, if I understood correctly, to add another sub-menu in "advanced menu", it should be enough to:
1. add another line which appends a new item in "_get_advmenu" (e.g. items.append(("NewSubMenu", "NewSubMenu Brief Description"));
2. add a new function "_get_ifconfNEW(self, ifname)" which can be based on "_get_ifconftext" as template;
3. add "self._get_ifconfNew(self.ifname)" in "ifconf" (e.g.

retcode, choice = self.console.menu("%s configuration" % self.ifname,
self._get_ifconftext(self.ifname),                                                         self._get_ifconfNEW(self.ifname),                                                         self._get_ifconfmenu(self.ifname))

).
Am I right?

Instead, if I'd like to use "services.txt" to add my new features, I should edit services.txt in something like:

Web:       http://$ipaddr
               https://$ipaddre
               ...
New:       $newVariable
 

Am I right? 
Howerever, is it right my guess that $newVariable should be an enviroment variable of linux? Otherwise, how do I define such $newVariable?

It is a lovely news that you are currently tweaking confconsole! ;-)

P.S. Thanks for removing the spammer, and, of cource, for your help!
