I know it might look intimidating to tackle oUF layouts the first time you look at them. But downloading and looking at the Lua for a while, do some trial and error, and you'll soon get the hang of it. Most users (like me) don't want to change functions or add stuff, it's mostly about styling them visually.
I really encourage you to try, you would soon find that oUF is a very powerfull unitframe addon. I'll be glad to help you with what little knowledge I have
