Hello lovely! For this theme, you have the option of either a top hover bar or five side hover tabs.
To change between the two options, simply save and refresh your customize page, and there should be boxes with checks next to it that say "sidehovertabs" and "tophovertab". Check off the one that you want (make sure the other is unchecked) and then save and close. Done :)

Put more stuff here! Just go to Edit HTML, then search (command+f) for "put more stuff here", delete all this, and replace with whatever you want.
