I'm trying to make "Dim Wallpaper" for WinterBoard dim the wallpaper even more, so I made a copy of the "Dim Wallpaper.theme" directory and changed the opacity in my Widget.html from 0.3 to 0.03. It didn't help even after I turned on my modification in WinterBoard, turned off the regular "Dim Wallpaper", and resprung. However, if I instead change the background-color from "black" to "red", I can see a difference in the wallpaper (a red tint).

I'm running WinterBoard 0.9.2958-2 on an iPhone 3G with 3.0 firmware.

Is this just a limit on how low opacity can go, or am I missing something else?
