If you have been waiting ever-so patiently for the past 24 hours to try out the new Gmail for desktop, you can do so starting now. While in your inbox on the desktop, hit the Settings (little gear on the right) and under the drop down menu, select “Configure inbox.” From here, you will select which tabs you want to have shown, including the new Social and Promotion options. What’s great is that you do not have to have any of them selected, so if you want a more unified appearance, then you won’t have to change anything.
Although, the new look does disable the Priority inbox, so that’s also something to keep in mind. If you don’t like the new look, you can easily revert back by going to Settings>Inbox and then under the drop down menu, select “Priority Inbox.”
Please note, this new look is currently not available for Google Apps users.
Feel free to give it a spin!
