It's so like Google to pretend efficiency tools are a perk. But hey, the holiday season is full of chores. Many people find it the most stressful time of year. Gmail comes to our rescue with a new feature: simple task-list functionality. The list opens in a small window on the side of your inbox like Google chat, but can be opened in a separate window to use outside Gmail.  You can also convert an email into a task. Now, if Google could only do our actual shopping, too.
