Hello. At this time, there is no option to change the font family.

Is it possible to manually insert HTML code into the widget and implement Google Fonts?

I'll check if they can open up a field for extra CSS on the widget setup page. In theory, it should be easy to do as the rest of the settings are loaded via CSS anyway. Will let you know when I hear back.

Hello. There will be a system update tonight that will add a text box for a custom CSS box in the leaderboard setup. Thank you for the great suggestion!

Thank you for the support and adding this in!
