Vienna RSS reader offers a free, vibrant red theme to enhance user experience.
Installing Vienna styles is a breeze - simply download the style by clicking on its name, and double-click the downloaded file to extract the ZIP file. If you're using Safari, the file will be automatically unpacked for you. The last step is to double-click on the extracted .viennastyle file, and the style will be installed automatically into Vienna.
Overall, Rocko-Dark is a fantastic option for those who want to give their feed reader a fresh look.
