Is your feature request related to a problem? Please describe.

The wall is limited in terms of live wallpapers. Seelen has a wallpaper engine but if we want to avoid the use of others it should have similar functions.

As of now, selecting a wallpaper will just fill both screens with one individual image.

Describe the solution you'd like

• Allow to select wallpapers per screen
• Duplicate wallpapers to show the same in both (options to adjust the wallpaper to the screens in general)
• Function to stop the wallpaper when detecting full screen apps

Describe alternatives you've considered

Using Lively, but since we are encouraged to use the built in options, we should make the functions better.

Additional context

These are two separate screens.
