A new option is available to enable or disable that will open up a second screen for multiple target tracking for debuffs and DoTs. with the new feature you can track multiple targets with what dots or debuffs you have on target, the time left, you can click on the targets name and switch to that target, then click on the time of the debuff and recast. all with in the window.
targets health bar will now change from green (above 66%) to yellow and yellow to red (below 33%)
