The Font/ Branding Text tool lets you save texts ( with your own font settings: size, color, rotation, effects, etc.) to the text library so you can use them anytime in your designs.
The saved font/text appears below the Default Text options on the sidebar. From there, users can also delete the saved font/text brands.
You can also watch this webinar replay (at 45:53 of the video) for a quick live demo.
