it is possible import the scrivener v1 theme.
the new apple barbie toy v3 theme is beautiful, but I liked more the old theme.
i didn’t find how to export the theme in 1.9.
Themes are not compatible between versions. You would need to build your own custom theme for v3.
Note that many elements of the UI (icons, etc.) have changed to be consistent with the Mac version and are not user-adjustable.
thank you. I will try adapt. is there some place where are listed all the improvements and differences of scrivener 3?
