Fonts.ini is very good for having the fonts specific to NWC not cluttering the system font list.
Recently (...today) I had to add a font to NWC, so I added it manually to fonts.ini.
Does it exist in NWC an "official" (read: user friendly) procedure to add fonts to Fonts.ini?
Sic! Look here (https://forum.noteworthycomposer.com/?topic=9843.msg70375#msg70375).
I told you my memory is bad.
But I must say I hadn't any answer, so I can try again... ;D
