I added the logo, through the “Wp Creativix Options” menu and I was able to add text to the right by putting it into Header.php at the end of the “logoname” div. With the nav bar straight underneath.
Changing theme files is not recommended as all your changes will be erased when the theme is updated. Instead you should use a child theme.

Good idea. I will remember that for next time (all went haywire when I tried to do it now – it says I must install the parent theme).
