SettingsController: Refactor the appearance settings
This merge requests brings a change to the appearance settings:
- The appearance settings action sheet now displays the black background option when available, in order to group all the settings involved in the appearance of the application.
- The black background option is therefore removed from the
Main
section of the settings.
This merge request also brings a small adjustment in the name structure of the MediaPlayerActionSheetCellIdentifier
.
