GNOME Tweaks 42 focuses on removing tweaks which are now duplicated by
Settings. Additionally, Tweaks 42 marks the GTK theme tweak as "Legacy".
In GNOME 42, the "Legacy Applications" setting will only apply to some
GTK3 apps and a limited set of GTK4 apps. Most core GNOME apps will
instead respect the user's dark and light mode preference via libadwaita.
Users interested in theming can continue to do so using more advanced
options such as the GTK_THEME environment variable.
