Ghost added Custom font support a few weeks ago, but they’re only a hard-coded list of fonts, loaded through https://fonts.bunny.net/. I’d love to be able to use any custom font (e.g. one that I bought and thus isn’t available through bunny, meaning I couldn’t request the typeface per e-mail as asked in this post) by uploading the font files to Ghost and setting it, without having to manually edit / create a theme and set the font through that.
This would fit even better to the “Custom Font” label, since then it would actually support custom fonts.
