这是Gmail Lab推出的一个实验版本，有13个新特性被加入Gmail中，用户可以在设置里面选择启用哪些新特性。

在Lifehacker上看到的这个消息，有兴趣的可以去试试。话说Google在用户体验上做得确实很到位，新加的特性里面，如自定义快捷键、多样化星标等，看起来不是很震撼人心的功能，但是确实很实用。

在Opera中因为不支持GMAIL的最新版本，所以不能开启Lab模式，在Firefox中一切非常好用。

完整的特性列表如下：

Quick Links

Adds a box to the left column that gives you 1-click access to any bookmarkable URL in Gmail. You can use it for saving frequent searches, important individual messages, and more.

Superstars

Adds additional star icons. After enabling this feature, you can choose which icons you wish to use in the "General" Settings page.

Mouse gestures
by Erik A
