ID_TAGGER_TO_USE_FOR_THE_MP3_FILES

This constant presently can be either :taglib or :id3lib.

:taglib is the default since as of 2021. I transitioned away from :id3lib for several reasons.

Depending on the value of this constant, a different library will be used for tagging the .mp3 files at hand.

This is the font for use in the top header-bar. The user will typically see this font first.

Miriam Libre is better than Noto Serif, in my opinion.
