Groups panel
The groups panel allows you to organize your fonts collection. Some people prefer to make groups for specific projects while others like to divide their collection into groups like Serif, Handwritten and Symbol. This and more is all possible with the groups panel. You can load/install/uninstall fonts through the groups toolbar, the main toolbar or by using the right-click context menu.
MainType 4 upgrade users: As opposed to MainType 3, MainType 4 does NOT store the groups folder structure on disk. Also it is now possible to put the same font in multiple folders without taking up any additional disk space.
