Currently, Customily doesn't display what the fonts look like in the font section, only the font's name. So it's a little time consuming when you wanna choose a font while making your template.

I suggest that you can be like adobe photoshop and just display the font's name in the font's style or a sample text next to them.

First photo is Customily's font section and the Second photo is Photoshop for reference.

Hope you can make the change. Thanks!
