4.3 New UI buttons

[Last Starfighter]

We get some new abilities that appear on our UI for dragon soul, MoD, and Ultraxion. These aren't friendly with action bar addons atm. Will this be an issue on live?

[Solenus]

Probably depends on if the AddOn Authors know how to fix it, if not there are macros for it, /click ExtraActionButton1 is what I was told in LFR on Ultraxion and it worked for me there.

[Obsession]

/click ExtraActionButton1 works and there is also a button you can bind in the Blizzard Key Bindings menu called Extra Action Button 1

[Ketho]

The latest Bartender4 alpha build supports ExtraActionBar,

however the main Locale file isn't yet updated (gives an error), which the author promised to do when it hits live #817

[Eon Drache]

I know ElvUI already has this fixed, and you can bind it in your Keybinding menu, so it really shouldn't be a problem unless you want to move/skin it.
