 5. Apps that use completely custom styles (e.g. **Contrast**) shouldn't try to follow the preference at all 
if it doesn't make sense for them.
 6. Libraries that provide widgets should try to follow the app's appearance if possible and makes sense - 
for example, **WebKitGTK** should use dark color scheme for pages that support it when the application it's 
embedded into is dark — either automatically, or via API that the app would use. They should not follow the 
system preference directly, as there's no guarantee the application follows it.
 
+If most of the application is content and not UI, the content should follow the preference as well when 
possible. Some examples where this applies:
+- Text editors
+- Maps
+- Note taking apps
+- File managers
+- Calendars
+- Games, e.g. Sudoku or Mines
+
 # Implementation
 ## GTK4 + libadwaita
 Applications follow the preference by default, so design 1 doesn't require any changes.
