Imho it's not necessary that users are able to install their own fonts. Just the possibility to chose different fonts for chords and the rest of the score and a handwritten looking font for chords would be great. It would be perfectly fine if MobileSheets included such a font in its installation, that's how it is also the case in MuseScore which also doesn't install its fonts in the OS's font directory but integrates them somewhere in the installation files. The font files on github are provided additionally in case somebody wants to use them for other purposes like ChordPro or (hopefully soon) MobileSheets. I proposed MuseScore Jazz because it is open source, well known from its usage in MuseScore, it is loking nice and comes with "real" sharps and flats.
Default settings for all songs with the possibility to overwrite them for the one or the other song would be great. The settings for page scaling and display mode and the new fixed page settings are implemented like that in a great way. I myself would use the same fonts for all my songs, overwrite colours every now and then and set individual font sizes for every song.
