NOTICE: This theme is not intended for the classic session.
My current desktop, custom gnome-shell theme based on default theme, install with Tweaks (gnome-tweaks) by loading the .ZIP file to install in the default freedesktop folder.
And to change the overview wallpaper (activities/overview) edit the file .local/share/themes/XGnome Enhanced Next/gnome-shell/gnome-shell.css in the #overviewGroup section indicate the path to the preferred image ( normally i edit the wallpaper with gthumb to be a little different from the original or define another one, it is up to you), tested only on gnome-shell 40, I hope you like it, it is no longer available on gnome-look, now only on deviantart with the most recent changes.
