Don't always scroll to the top

[extesy]

When the intro'ed control is already entirely visible on the screen, there's no need to scroll it to the very top. Otherwise on the vertically oriented (or just big enough) screens it becomes very inconvenient to read.

@extesy that's true I agree. I'll handle this when I have some more free time. Cheers

Hi, I have this same problem.
Im using bootstrap with a nav bar and as it scrolls to the top, part of the popover title hides behind the navbar.

Thanks
