Microsoft Office 2016 Pro Plus Beta
There are several themes to choose from, all of which can be selected from the settings screen of your Office installation.
At this point, the dark theme doesn’t seem really polished and it still needs some touches here and there, but it’s pretty clear that Microsoft is planning to give users more UI options in the new Office.
Just as it happened with the previous testing versions of Office, this new one comes with the typical smiley button in the menu bar, allowing you to quickly submit feedback if you like or dislike specific features. A similar approach has also been implemented in Internet Explorer 11 in Windows 10, again with the sole purpose of getting feedback from users.
