Features
Interface
The three-pane user interface is modeled after desktop email clients, with a tree view showing the list of feeds. The application has a number of features inspired by email readers and other RSS readers including:
Search folders for reading all items that match a search term or just all unread items
Import and export subscription lists as an OPML file
Keyboard shortcuts for main functions
Ability to download podcasts
Automatic marking of items as read as they are scrolled past
Search in all feeds, across all updates from subscriptions
Current subscription lists and read/unread state of items in the application can be synchronized via a FTP or WebDAV server, allowing use from multiple computers
