Full screen window mode

Full screen window is the most important function in MacOS. All applications can run in full screen mode. This does not mean that the window mode will disappear, but that it is possible to realize full grid computing in the future. The user interface of iLife 11 also shows this. This user interface will greatly simplify the use of computers and reduce the trouble caused by multiple windows. It will give users the same experience as iPhone, iPod touch and iPad users. The computing experience will not be weakened; Instead, apple is helping users handle tasks more effectively.
