Hi!
We have just released a tool to help the Envato community preview font files on GraphicRiver! This project was built during the Envato hack fort that happened a few weeks ago. Please let us know what you think!
E.g:
Some examples of it being used are:
http://graphicriver.net/item/porter-font/10277889
http://graphicriver.net/item/equilibrium-font/6211159
http://graphicriver.net/item/airport-arrival/2802161
It was originally announced to font authors https://forums.envato.com/t/project-moosetiger-hack-fort-2016/41959 and included are instructions for authors to best display their fonts.
