Creating a folder on the Home screen does not require the purchase of Nova Launcher Prime. Only creating folders in the app drawer is a Prime-locked feature.
You can change the way the preview icons are displayed as well as the background shape/color by tapping “Folder icon appearance”. You can toggle and edit the app names/colors by tapping “Icon Layout”.
Making folders in your App Drawer requires Nova Launcher Prime, which is a one-time upgrade purchase in Nova Launcher.
