Switch background fill mode as well

[pohuing]

Describe the enhancement or feature you'd like
Switching between bright and dark mode should also switch the fill mode.

Accordingly it should move down to the wallpaper section

Describe alternatives you've considered
Converting all of my wallpapers to 16:10.

Additional context
Neither of my wallpapers are 16:10, which means I always either have ugly borders where I don't want them, or a blurry mess.

What I want:
This is a 1:1 image, so I want
Fill mode: center, "Anpassen"

And this is a 16:9 screenshot, so I want the sides cut off with
Fill mode: fill, "Füllen"

Thank you for your proposal. At present, this part of the function is not included in the underlying design, and may be updated in the future.
