enhancement: I'd like an option that would create header and/or footer to identify before and after font

[marekjez86]

Currently I'm embedding the font info in the name of the output file. However, I'd like to suggest an enhancement where TTFDIFF would create in PDF a header and/or a footer to identify before and after font (family, version, weight, date(s) embedded in the font [if any] etc. whatever is useful)
