Feature Request
Add option to extend the wallpaper to all monitors, making just one image instead one for each monitor.
Software example: https://johnsad.ventures/software/backgroundswitcher/
I don't know if depends on system or anything, but Login Window can do what I say

Login Window

John's Background

Option implemented, will release with version 1.3

I saw your implementation, it "works", but unfortunately it leaves blank spaces.
I was trying to do something like join zoom and spanned options, but no results.

I also saw the options that org.cinnamon.desktop.background has and maybe we need to do more than just messing with it.
Dynamically resize image, I don't know, seems too much effort for too little result.

Compare the image below with the one I posted on Expected Behavior
