It is such a pain to open the window from the dock, just so I can close it. Surely there is a way to close it without opening it, and I am just missing the trick. Any help appreciated.
If you're trying to quit an application, all you have to do if hover over the icon with the mouse, right click then click quit.
But if you're trying to close a minimized window of an application, there's isn't a way to do it that I'm aware of without bringing back the windows from minimized.
