Can anyone help me hide/remove a button?
 

I was curious if anyone knew how to remove a button in my screenshot, that button that changes between that first action bar? I've never change that bar, not in my whole time playing wow, and I notice, those buttons are old and cumbersome, is there a way to remove those buttons?(Just an FYI, this is a mod of my skin for my RL best friend).

There is, at present, no facility to remove them from the user perspective... it would required editing the source for the action bars in nUI_ButtonBar.lua which would be broken every time there's an update. I never recommend making changes to the core code -- changing the layout files is one thing, changing core code another.

I will look into adding the ability to disable that as a command option rather than breaking the code.

Cool, I just never use it, we have all, or most of all the buttons we can ever need already showing, I figure it's not useful anymore :D.

In this particular layout, that would be true. In other more minimalist layouts, not so much.
