I was excited when I saw this, because it’s a VERY easy tool to solve an often overlooked want. One thing killed it for me though; it forces you to use every monitor available. I have two monitors attached to my macbookpro, which are situated above my laptop side by side. I only want to set the wallpaper for the monitors, and leave my macbook built-in display’s wallpaper independent. FEATURE REQUEST: Ability to include/exclude monitors used for wallpaper. Please make this happen! :)
