The app allows you to preview fonts in a grid or custom view, add and remove font collections, install and uninstall with a simple click, save your favorites, and download the current Google Fonts collection to add to the app. It also includes four new commercial use OpenType font families. For a limited time you can download Font Manager Deluxe for $10, a savings of 50%.
