hello,
I really like Display Fusion and especially Wallpaper Profiles. But often while editing a Wallpaper Profile I think "Oh, this would look better on the other screen". In these times I wish, there was a small button that simply swaps images between 2 screens.

How about a behavior like this for more than 2 screens:
1. Klick button
2. Select source screen
3. Select destination screen
4. DP swaps Images

bye

Maybe instead of clicking a button to swap you could just set it up so that you drag one preview window onto the other in the wallpaper settings. It would probably be easy to code that for multiple monitors once you have dragging.
