Menus viewable as tabs?

Hello,

Some users of the wiki site I've set up using Theme Builder have commented that the menus aren't easily recognizable as buttons/menus and didn't know they were able to click on them to access more portions of our wiki.

My question is: Is it possible to change the menu so that they appear as tabs, something similar to what the Adaptivist site has running along the left side of the page, but in the Menu Bar location? If so, I would request that someone please point me to the documentation where I can add this to my own wiki site.

I'm using Confluence 2.9.2 and Theme Builder 3.2.1.

Thank you.
