It seems Microsoft is planning to bring changes to many of the native apps in upcoming Windows 10 Redstone builds soon. We saw some changes coming to Outlook Mail and Camera apps. Now it seems Microsoft is going to change the UI of native Movies & TV app too.
Check the new UI layout shown in leaked image above and compare to the old layout shown below.
The icons that look converged to center in the existing Movies and TV app are scattered in the new UI layout. There is a new Forward-Backward logic in center and a pivot menu in the right corner that houses Cast, Aspect Ratio and Repeat options.
