Resolved Helix Ultimate 2.x - Header scroll down > to hide

Hi guys,
about Header:
to save useless space is really too important, Google has long added the feature on all her Apps like Google Drive and Google Photo, here a video example for you.
When scroll down the Header should always disappear (on all screen dimensions) while a small scroll up restores it
Please, Can you consider it for the 2.0 stable release ?
