Currently QtCurve supports window opacity in the configuration but that's just for the window backgrounds. For instance that opacity settings don't work for the Dolphin's background(except the side and top-bar) and for kinfocenter.It would be nice if QtCurve supports adjusting the opacity for "QGraphicsView"s. Also the ability to disable that feature for some programs like what's possible for opacity settings(i.e "No background opacity" in the "Configure QtCurve->Applications") is great. Thanks.
