I'm sorry if this has been discussed before..

Thanks to the updates in ios, you can install custom fonts via profiles in settings. I just imported powerline fonts (I'm a Japanese user so I would really like to have a Japanese ready mono-spaced font) from my computer and installed it to my iPad, but it looks like the font chooser on this app doesn't show the custom installed ones. I don't know if there's a function that filters mono-spaced font out of the custom installed fonts, but I would really appreciate if there was a feature added to support them!
