System Settings/Font Management
This configuration module allows you to manage the fonts installed in your system. You can add new fonts, delete existing one. You can also see how the font look.
You can use the group functionality, to sort the fonts in categories. By default, only 3 categories exists: All Fonts, Personal Fonts and System Fonts. The first time you create a new group, you also add a new 'Unclassified' group, where all fonts not categorized go.
You can drag and drop a font to a group, to add them to the selected group.
