Features:

Import your favorite newsfeeds using the OPML format. Most newsreaders support the export of newsfeeds via OPML, making it very easy to switch to RSSOwl and have your bookmarked favorites inside RSSOwl.

Bookmark your favorite newsfeeds in nested categories. Set properties like "autoupdateinterval", "open on startup" or "reload on startup". RSSOwl helps you finding a suitable title for your favorites. Just click the "Grab title from newsfeed" button and RSSOwl will scan the newsfeed for the title and use it for the new favorite.
