I use the XFCE4 desktop environment in my Linux distro. By default, when you minimize an application in XFCE4, its icon becomes dimmed on the taskbar. This is to indicate which windows are minimized with a quick glance at the taskbar. However, not everyone likes this behavior. Some users prefer to see minimized app icons in full color. While XFCE4 does not come with an option to disable the dimming of icons, there is a quick hack which will allow you to change the appearance of the minimized window icons.
