Whenever I'm in a Vehicle other than a normal Mount the PVP Button on the Micro Menu appears separate and below the the menu bar, if I'm not using the Blizzard Override Action Bar. When not in a Vehicle there is no PVP Button on the bar at all on the bar.

I'm using ver: 5.4.11

I think I've actually fixed this in the latest alpha. Since it is targeted for the beta, you'll need to enable out of date addons:

I updated to 6.0.0 but still having same problem. I also disabled all other addons, no change there either.

Thanks for the fix, worked perfectly. It was a very minor issue, but I'm a little obsessive about my UI :)

So thanks again, for the best bar addon around.

Upon further reflection, that's probably because the pvp button goes away in the next WoW patch. Try uncommenting the lines 18 https://github.com/tullamods/Dominos/blob/wod/menuBar.lua#L18 and 36 in https://github.com/tullamods/Dominos/blob/wod/menuBar.lua#L36 menuBar.lua
