You’re in luck (hopefully) since we just launched built-in Google Web Font support for 20 fonts without any custom work on your end. Assuming the font you are looking for is in this list. Check out the following page for the preview of fonts we’ve released:
If that will work for you, make sure you are using our beta editor and then you should find these 20 fonts in all the standard font drop-down menus for text, buttons and form labels.
In the future we will be providing support for easily adding a google web font that isn’t included in our initial list. Let us know if this still doesn’t work for you right now.
