We've looked at plenty of Chrome new tab page extensions. If none of them scratch just the right itch, Knew Tab is a good one to try.
The extension turns your new tab page into an attractive, minimal list of essential information. You'll get the current date and time, Facebook notifications, unread messages in Gmail, a word of the day, a news ticker and current weather. If you like the look and you don't need a lot of customisation options, this is a worth checking out.
