I sometimes find it difficult to read low contrast items with the current QColor(0,0,0,180) that is used as the background, and have wanted more than once to make it more transparent. Of course, that may be outside the scope of a kwin effect plugin. ;)

I redraw this patch as I started working on a KWin plugin for the dashboard, where you can switch blur on/off, select the translucency and the background color.
