Is it possible to change the font size on the menu bar drop downs? And maybe resize the menu bar? Hey I’m old I can’t see the darn things very well!
Are you using a Retina display? I’ve found that selecting a larger “scaled” user interface in the Display System Preference panel is much less ugly looking that it used to be. The short answer to your question is no, however, the menu bar is a Mac feature, Scrivener just gives it the information (all of the menu commands) to display.
