This mod creates a set of buttons and health bar for each party/raid menu to help healers of all classes. It tracks if spells are active, or if a spell can cure a debuff on someone. It has a favorites window option that allows you to choose who and what order are on it. Many find it much easier to visually see buttons and the indicators on the buttons. The number of buttons and spells of the buttons can be modified in the menus.
With a full raid it is recommend to not use button modifier options, and to try to reduce the buttons only to what's needed since it can slow the interface down on slower computers. I'm working on improving the performance. Adjusting the update interval can also help with the performance, but this will effect how quickly the indicators are updated.
Feel free to borrow, steal, or improve anything from the mod.
