Idea

• Automatically switch between Light and Dark theme variants
  • Time of day
  • Using Theme.AppCompat.DayNight to follow system-wide theme, e.g. as per LineageOS' Styles API

Rationale

Dark theme can easier on the eyes at night, but the light theme is better for reading in daylight/sunlight. Manually switching works, but can be a slight hassle.

Time-based is sufficient, though integrating with the system-wide choice on devices that support it makes for a smoother experience by having everything follow a single setting.

Additional

The LineageOS' Styles API also has the option for setting an accent color without needing the Lineage SDK. Might be neat to integrate this somehow.
