Settings in PowerPoint 2016
You can increase the number of recently used presentations up to 50, and you can pin (fasten) particular of them to the menu so that they remain there even if you haven't used them recently.
By default, PowerPoint shows document tooltips (or ScreenTips) when you hover on a button, but this option can be turned off.
When you need as much space as possible on screen to view a document, you can collapse (or minimize) the Ribbon and then restore it very simple.
When you first start most of the Office 2016 applications, you'll see a new feature called the Start screen.
