The button in the Ultraxion and Madness of Deathwing encounters is not the same as the power bars in previous raids! This addon will do nothing for those. Luckily I do have another addon (BetterExtraActionButton) for moving that button

Makes the PlayerPowerBarAlt frame movable. This is the frame for quests and instance encounters that shows a power bar specific to the event. This includes sound on Atramedes, corruption on Cho'gall, Lord Rhyolith's direction, and feathers on Alysrazor as well as the counter and timer bar used in Dark Moon Faire games.

There is no config. Right click on the frame to make it movable, then drag it to where you want and right click again to lock it in place. While it is unlocked, you can also use your mouse wheel over the frame to adjust it's scale and reset it back to its default scale by pressing the middle mouse button.

4.0.6 added an option to show the status text (Interface -> Status Text -> Alternate Resource), so you can change the setting there or toggle it by holding shift and left clicking on the frame. By default the status text will show when mousing over the bar.

To adjust it outside of a raid encounter, you can fly into the Maw of Madness in Twilight Highlights and move the "Digestive Acids" bar around.

If you find the frame some place it shouldn't be, you can type "/bpba reset" to move it to the center of screen.

Also a quick note: Unit frame addons like to disable the blizzard bar (PitBull does by default), so if you're not seeing it, that's more than likely why.
