This comes to my attention and I am curious. In Home and All Apps, I don't have to use scroll bar to scroll with a mouse. I can keep moving to the right and it will scroll. But, that's about it. All the apps I have tried, Movie, Photo, SkyDrive, etc doesn't do this. They only support mouse wheel scrolls.
Is this feature limited to Home and All Apps only? Is this just an implementation? Meaning can I make my app scroll same as Home? How? And why doesn't Movie and Photo app doesn't support this? What's the reason they choose to not to support Home Mouse Scroll style in their apps?
Just trying to understand what's going on. If you know why, please share the insight, thank you.
