Повторюсь: возможно будет реализовано в следующих сборках.
New Start menu: You’ll see some big changes to the Start menu in this build, including the ability to expand to a full-screen experience. This really shines on 2-in-1 PCs when switching into Tablet Mode. You can also customize the color of your Start screen. A big change that you won’t see is that we actually rebuilt Start in XAML, which is one type of code developers can use to build apps for Windows 10. The work on Start isn’t done yet, and we’ll have more changes that will show up in future builds including more personalization (and transparency!), drag and drop, Jump Lists, and the ability to resize the Start menu.
