Self-published authors normally employ Microsoft Office to write their next novel. Depending on your operating system of choice, the actual design of Office changes dramatically. When Office 2016 comes out later this year it will amalgamate the overall design from the Android and iOS apps into the PC version.
A leaked version of Microsoft Office 2016 has just been released and there is a new “colorful” design. It’s also similar to the Windows 10 touch-optimized versions of Office, with a colored look that matches the Word, Excel, and PowerPoint applications.
I think unifying the design principals from the mobile line of apps and integrating them into the desktop variant is critical to the continued success of Office. Not too long ago Microsoft was heavily resistant to the mobile space, but under new leadership have fully embraced it.
