I can't download this new version for Qt6; the download link gives an error. I hope you can fix it soon—I'm really looking forward to trying it out!
As for the idea of adding background images, whether in the list view or in the profiles, that wasn't my idea; it's a feature that's already implemented in DFendX, under “Program Options,” in the “User Interface/Game List” or “Media Preview” section.
I just wanted to let you know that it wasn't working. My idea was to put a small image of the clouds from *The Curse of Monkey Island* behind the game covers.
Still, I think that since it's a small image, it would need to be repeated until it fills the entire space for it to look right.
