Stop distinguishing between the display list and per-display fragments. Instead, always show all displays that are available. This is closer to how the UI will eventually look, which is each display in a tab. Setting an OnChangeListener for multiple preferences with the same key did not work, even though the conflicting preferences had different parent preferences. Only the listener of the top-most preference was notified even when changing a different one. So this CL changes PrefBasics so that it can set unique keys for otherwise identical preferences.
