When I tried the new phone app in Windows 10 I tried several times to slide the screen toward speed dial. I realized that this is not possible, it is not me, my hands are clean, it's them
.
Also, 3rd party apps are greatly designed with pivot in mind. Do you imagine a Central Windows with hamburger menu? When it is so natural to just slide left or right for comments or more.
(Oh, and I know an app like that, it is called "Windows Central ? The app!", and it is found in Android store)
