Newsflow has been designed to be a fluent news ticker application. It always stays on your desktop, rather than running in a window like Leaf. This behavior helps you quickly scroll through your articles and have them always visible.
The news reader of Newsflow only shows up when you click on articles, giving you a quick, but full featured preview.
RSS Notifier is also a news ticker, but due to compatibility issues with OS X Yosemite, El Capitan, it will not be supported in the future. Newsflow has been designed to replace RSS Notifier.
