After the latest updates on my Manjaro-Gnome box, I noticed that the colour of the title bar in applications had changed a bit. When using the Adwaita theme, the title bar of unfocused applications is the same light grey colour as the menu bar. (Was this the default colour for the title bar in all states?) When an application gains focus, the title bar is a little bit darker.
What I would really like to see is a stronger contrast in title bar colour between focused and unfocused applications. I did not find any settings for this in the Gnome Tweak tool or the dconf editor. Is this possible? Does this require creating a
gtk.css file as suggested in the article Making GTK3 themes – Part 2: The gtk.css and gtk-widgets.css files (July 2012)?
