The "-F" command line option is documented as "use factory settings", but it actually performs an irreversible factory reset
Trying to determine MuseScore's default font size, I ran
musescore3.exe -Fon the command line.
Expected behaviour: MuseScore would ignore my user settings for one session, then restore my settings the next time I start MuseScore.
Observed behaviour: A full factory-reset was performed, without any warning or confirmation dialog.
Suggested solution: Improve the documentation of the
-F flag to make its consequences more clear. Consider adding a confirmation dialog.
