Scroll bar stacks

I doubt it being it's a beta OS. Maybe in the released version, but I doubt it. What would be the point?

 

No, and why would you want that?

 

They need to make the scroll bars appear when you need them. Most of the time I don't even use the scroll bars because I can just scroll in place using my wheel mouse or double finger.

 

How are you supposed to know something is scrollable if theres no scroll bars, or know how much scrolling you have to do? They do more than just offer the ability to click and drag.
