Hi Bassot,

To reduce the blank space that you want to remove please go to Appearance -> Customize/Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save button:

#content, .entry-header {
    padding: 0;
}

And to put the language button at the top of the header. It needs code customization you have to hire a developer as this is a new feature to add in the theme.

Thank you!
