It is possible to do this, but someone needs to do it ;)

The API-method api/?op=getConfig returns the icons_url path which has to 
appended to the url like http://server/icons_url/xx.ico (where xx is the id of 
the feed).

I tried to work on this feature request. I'm having a rough version at the 
moment, but I'm not happy with two things

1) downloading the icons isn't as fast as it should be. 
2) the icons are not available in good enough quality

If you look at the attached image, you can see that displaying the favicons is 
really ugly. I think this problem couldn't be solved, because the icons are to 
small (eg. 16px or height)

Would it be possible to display the feed title next to the update date in the 
article view?
This could also solve my problem. I need to know from which feed the article 
is?!

What is your opinion on this issue?

1) downloading the icons isn't as fast as it should be. 
Shouldnt be a problem if we do it in background and display the icons as they 
come in, has to be done only once so speed does not really matter i think.

2) the icons are not available in good enough quality
That seems to go for all favicons as they are usually supposed to be displayed 
in the browsers navigation-toolbar. But since they are small we can just keep 
it that way and display all icons in 16x16px or something. The rows should get 
a fixed height with the icons centered in the icon-area then i think it doesnt 
look so bad.

Another way would be displaying the old icons for feeds and inserting the 
favicons in the row before the feed-name so we would have 
<feed-icon><favicon><feed-name> in every row. The feed-icon would define the 
height of the row and the favicon would be smaller and right next to the 
feed-icon. And in the FeedHeadlineView we could display the icon in the 
titlebar next to the name of the feed. What do you think?

"Would it be possible to display the feed title next to the update date in the

Hm, versteh ich das richtig, du willst das Datum der letzten Aktualisierung da 
mit anzeigen? Wird das nicht bischen unübersichtlich? Und welches genau, das 
des letzten Abrufs des Feeds durch den Server oder das Datum wann der Feed 
zuletzt vom Handy aktualisiert wurde? Letzteres wäre bei allen Feeds der selbe 
Wert weil fast immer alle mal aktualisiert werden.
Zu welchem Feed ein Article gehört steht in ArticleItem.getFeedId(), mit der 
ID kannst du in der HashMap DataController.mFeeds suchen, Key ist jeweils die 
Feed-ID als String. Hoffe ich hab die Frage richtig verstanden :)
