Some improvements on "5 hacks for twenty seventeen theme"

Hi, thank you again for those 5 hacks in https://premium.wpmudev.org/blog/five-hacks-twenty-seventeen/

– I would like to diplay video in inner page header as it is possible on homepage. Is there a special hack or setting to do that ?

– the sidebar works fine on inner pages but not on home, see the site : http://desbos-detective.fr . Did I miss something ?

– isn’t there a small bug that plays on site-branding.php homepage condition and lead to display 2 H1 in inner pages code one for site-title and one for entry-title ?

This doesn’t occure on the original twenteeseventeen theme.

Best regards
