Hi,

1/ That's demo bar we've created for our demos only - it just showing the demos from our theme and it doesn't include in the theme.

I think you can do the same thing by use Menu Hamburger.

Please go to Customize > Vertical Nav & Hamburger Menu Options > and check to "Enable Menu Hamburger"

It will appears like that when you click to bars icon: http://prntscr.com/nxzmh1

When you done, you can go to Appearance > Widgets > drag & drop widget "Custom HTML" to "Sidebar Hamburger Widgets Above Menu" or "Sidebar Hamburger Widgets Below Menu" > and put the ads code there.

2/ That's "Related Posts Popup" - you can enable & check options for it via Customize > Single Post Options.

Best Regards,
