QuiteRSS

teRSS is an open-source software designed to help you follow the news on your RSS reader. With this reader you can manage all the news you follow, easily and quickly. QuiteRSS adds all your RSS sources without exception; it can export and import all of them from wherever you need, and refresh them when you open the program or every certain number of minutes. This application lets you filter your favorite links and those you haven't read, and tag news under different categories. It has an integrated browser, so you can view your feeds comfortably, adjusting the space of the preview by activating or deactivating the images next to the articles. Besides being able to configure the proxy server manually or automatically, QuiteRSS shows you the number of news that you haven't seen on the icon, so you can never miss one.
