Well, my request for more text properties is from 2022, my request for a chord chart feature (that that seems to have triggered chord grids to be included into ChordPro by Sciurius) is from 2015 https://www.zubersoft.com/mobilesheets/f...-3124.html - so it won't be too dramatic to wait another month or two ;-)
Pango is a great extension of ChordPro, but it's not a convenient replacement for general text properties. Using lots of Pango directives within a song makes the source file pretty unreadable and breaks the compatibility with other ChordPro programs or websites (like e.g. Ultimate Guitar) that don't support it.
I could imagine that not all properties have to be 'per song' settings. Text size definitely has to be per song, whereas colour or font could be general settings different for e.g. comment, comment italic, lyrics etc. but the same for all ChordPro songs in a library. That would save a number of database changes, but I'm not sure if it really would make the implementation easier.
