最近Google的Gmail Labs又发布了几个新功能，看上去很不错啊。
1）YouTube, Picasa, Flickr, and Yelp previews
Instead of just links, see previews of photos, videos, and reviews right in your email.
YouTube， Picasa， Flickr预览功能，也就是说不必点击链接，直接可以在Gmail内预览邮件内链接的内容。
2）Undo send
Oops, hit "Send" too soon? Give yourself a grace period of a few seconds to cancel sending, then edit your message before sending again.
这个比较贴心，有几秒钟给你后悔。
3）Tasks mobile
Take your to-do list everywhere you go. Just go to gmail.com/tasks from your mobile browser.
可以用手机来查看任务。
4）Offline
Make Gmail work even when you're not connected to the internet.
这个功能之前我试用过，感觉不是很好，暂时不推荐。
