Vertical Scroll Full Screen Section: How to position the menu/logo?

Sure for the version? THis is what I have: http://tinyurl.com/y3h6a3s6

Now I'm seeing the full-width navigation containers.

Doesn't look like you've done this yet:

As for the version, you are showing the theme version:

OK almost there, made the requested updates. Now just need to resize the logo and slightly move it to the right.

As mentioned before, you can increase the logo size by increasing the menu item height:

Then CSS should move it to the right a bit:

.navigation-branding {
    margin-left: 25px;
}
