It would be nice to have a small search option in NewsFox, to search for a word in the headlines and/or the abstracts, of a single RSS feed or the entire archive/tree.
A very simple search option should do it. put it in the gray field where the feed name is.
Re: Search Option
Create a search group. The results of the search will be in the group.
Or you may try Options -> Keywords. This will highlight the keywords in all articles.
