Thank you for submitting this idea - we've just implemented your suggestion. We now display the default fonts for each template in the font selection panel.
Hope it helps and thank you all for your patience as we worked on this :).
Thanks for posting your idea! We know that site editing, fonts in particular, is important for maintaining the consistency of how your site and it's content looks. We're looking into this and we'll get in touch with you once we start working on it. Thanks again for your suggestion!
I'd like to know what's the default font is too. As ssdellacasa said - it needs to be consistent in print as well.
Would also like to know the default font family name...am printing business cards so would be helpful to be able to match across the board, thanks!
