Changes for mists of pandaria

• Fading in. All bars can fade in. Holy, shard, ember, eclipse, shadow, and chi bars also have fade-in for their objects.
  
• Reverse Fade. Bar is half faded out, now it wants to become visible again, it will start fading in from where the fade out left off. The reverse fade option turns this off incase you don't like it.
  
• Reverse Fill. Don't like left to right or bottom to top fill. Then reverse fill is the opposite. Ember, and Demonic bar support this in texture and box mode.
  
• Enable bars. Found under Bars as the first option. Bars that are not enabled will not appear in the options screen or on screen, and won't consume cpu.
  
• Hide not Usable. Any bar that uses this is on by default. When a bar can not be used by your class or spec. It will be hidden even when bars are unlocked.
  
• Hide in Pet Battle. Hides the bar if you're in a pet battle.
  
• Druid or Monk Mana bar. This used to be call Main Power. This gets displayed when the mana bar is not available. You'll have to reconfigure this bar going from old version to new.
  
• CPU usage reduced quite a bit.

New bars.

• DemonicBar and EmberBar for warlocks.
  
• Shadow orbs for shadow priests.

Please post any feedback in the comments section below.

Libsharedmedia 3.0 supported

Features

• Priority flag system. Each bar has a status flag to tell when to hide, show, etc.
  
• All bars can be fully customized to how you want them to look.
  
• All bars can be rotated. For health and power bars fill direction can be changed to match the rotation.
  
• Profile options. By default profiles are per character, but can be shared among all characters.
  
• Alignment tool allows bars to be lined up for perfection. Right click a bar when bars are not locked to activate the tool.
  
• Some bars have a box mode. If you don't like the fancy texture look. You can use box mode which uses simple boxes.
  
• Two textures 'GUB Bright Bar' and 'GUB Dark Bar' any mod that uses libsharedmedia will be able to use these.
  
• All bars have frame strata. If you want a bar to appear above another add ons UI. This should help.
  
• Bars can be copy pasted as a way to copy settings from one bar to the other. All health and power bars are compatible. But a copy paste between others bars may or may not work. Some of the copy paste will be greyed out if the two bars are not compatible.

Class Specific features

• Power bar for hunters has predicted power for steady shot and cobra shot.
  
• Eclipse bar has predicted power. Will show what state the eclipse power bar will be in while casting. Should work similar to balance power tracker.

Tips

• Eclipse bar: When you have predicted power turned on. Some of the options mirror the normal options. These should override the normal options.
  
• A lot of bars have borders these can be hidden. For example: In the shard bar when in box mode. There should be an option called 'background'.
  In there you will see a pulldown called border. Select 'none' and the bar will have no visible border. You can do the same to bars that are not in box mode as well.

v129 is out. Nothing has changed from latest beta.
