This has all the companion bars hidden as well as a lot of the other stuff that doesnt need to be seen for pvp. All 4 action bars, player and target (+target of target), and mini map are towards the bottom middle of the screen. I just enjoy having the UI as clean as possible with a little clutter as possible so if you're the same way try it out.
