Twitter.com launches its big redesign with simpler navigation and more features

Twitter's website is getting a major overhaul. The upgraded experience simplifies navigation with a new -- and fairly large -- left-hand sidebar that directs you to all of Twitter's key sections, including Notifications, Direct Messages, Explore, Bookmarks, Lists and more. The popular dark modes, Dim and the very black Lights Out mode, are now supported along with more ways to personalize Twitter through different themes and color options.
