Some of you may know of the GNOME Desktop Environment. It's one of several projects to create a desktop experience for Unix-based systems like Linux, BSD, and so forth.
GNOME v3 is due to come out later this month, and it's arousing a certain amount of controversy. The designers behind the project have decided to remove the maximize and minimize buttons from application windows, and leave the resulting space blank. In order to maximize and minimize, you have to use the mouse or keyboard.
