You had mentioned, "You can already create a custom font control in the admin area to change the font for all of the elements in one fell swoop. You can also hook into filters and add your own selectors to the default font controls if you know php."
Unfortunately, I don't know php. What I did was create a "body" font control and "body" CSS selector, which did the trick. Not sure if there's a cleaner way to execute this functionality within the plugin? Thanks so much!
