Microsoft Office 2013 now completely complies to the Metro style. The parts of Office now look more like Visual Studio 2012 and they are better touchable.
Yesterday I saw this feature in Microsoft Office.
You can find it in all part of Office 2013. Clicking on this menu item makes the space between the menu-items, buttons and icons larger. This way on a touch device, it is more touchable.
The funny part is, that if you have more Office products open at once, they all react on the selection of the item.
This also works with Windows 7.
