feature: Header auto hide and unhide as user scroll.

The header may be useless when exploring a slightly longer page or even while watching a video out of full-screen mode.

We have seen responsive headers like on the official Medium website. The header which goes up while scrolling down and comes back on when scrolling up.

Hi @Aayuslad - I agree the current header can be improved. I'm interested in implementing a responsive header similar to Medium's design to provide a better user experience. Please consider assigning this issue to me, would be excited to contribute.
