Google is introducing a new way to manage your Gmail inbox. This new view of your inbox puts a number of tabs at the top of Gmail’s inbox column. By default, Google shows tabs – and automatically categorizes your messages into them – for your social updates from sites like Google+, Twitter, Facebook or YouTube, promotions from the likes of Google Offers and Groupon, and a kind of catch-all “Updates” tab for your bills, receipts and similar messages. You can also add a tab for forum notifications which, at least in my test, also includes email lists. Google, of course, allows you to add or remove as many of these tabs as you want. To go back to the classic inbox, you just have to turn off all of the tabs or switch to another inbox style. This update, which will start rolling out for all Gmail users on Wednesday, will be available on both the desktop and through Google’s mobile apps for iOS and Android.
