Request: display first line of news item in items list

When reading a lot of news (from places like BBC News) there's a lot of
articles that I'm not interested in. It's useful to have a preview of
the content (not just the title) to see if it's something I'm going to
be interested; and some feeds only provide a few sentences anyway (e.g.
a 255 character limit).

It would be more useful (to me) to have a line summarising the post
(and a quick way of marking it as uninteresting) instead of the title
of the feed repeatedly.
