OK.

There’s no such thing in ‘core-updates’.  However, one could set a
‘fontconfig-update’ branch and update Fontconfig and possibly related
libraries.  We could merge it in ‘master’ more quickly than
‘core-updates’.

Yes, sounds good.

Native?  If it’s for one of the binaries, such as ‘qmake’, please
mention it in a margin comment.

“Poppler-Qt4” maybe?

“... for the Qt4 interface of the Poppler PDF rendering library.”
So that at least “PDF” shows up in the description.

OK with these changes.

Would be nice to mention a couple of features, like: “Among other
things, it can render scores next to the source, can capture input from
MIDI or read MusicXML and ABC files, has a MIDI player for
proof-listening, and includes a documentation browser.”

OK with this change.

Thanks!
