At the moment in the contactlist is it so that new accounts always get the name of the mail or xmpp adress. in some cases that are something like "111001455403723237588456737@domain.com". now my idea is to show the real Name of the domain. not the adress. in cases of 2 accounts at the same domain (or 2 windowslive/icq) tha account name could be displayed as tooltip or it could be  an additional mode

So you will not see "myrealgoodname@gmail.com". you will see "Google".  (or am I the only one who prefer to see the serviceprovider instead of 5 adresses?

well in case the Idea is good. I'm working on a xml file for it:

<?xml version="1.0" encoding="UTF-8"?>
<XMPPProvider>
    <description>List of serviceproviders with names</description>
    <provider>
	<name>Animexx</name>
	<website>https://animexx.de</website>
	<favicon>http://animexx.onlinewelten.com/favicon.ico</favicon>
	<xmppServerAdress>jabber.animexx.de</xmppServerAdress>
	<xmppServerPort>5222</xmppServerPort>
    </provider>
    <provider>
	<name>Google</name>
	<website>https://plus.google.com</website>
	<favicon>https://plus.google.com/favicon.ico</avicon>
	<xmppServerAdress>talk.google.com</xmppServerAdress>
	<xmppServerPort>5223</xmppServerPort>
    </provider>
    <provider>
	<name>Neko IM</name>
	<website>https://neko.im</website>
	<favicon></avicon>
	<xmppServerAdress>neko.im</xmppServerAdress>
	<xmppServerPort>5222</xmppServerPort>
    </provider>
</XMPPProvider>

(only 3 atm but will grow bigger the next days (: .. so you see i use the tag favicon. for xmpp provider we can display this little icon and not the xmpp bulb. this will help to find the service if we have more xmpp accounts on the list (like a friend with 27 accounts..).

Maybe we can use this xml file to make something else. like preconfigurations for known providers. but thats an other story. 

Reproducible: Always
