Provides a status in Grid to highlight units affected by your Chain Heal. The highlighting lasts for a configurable duration; the default is a little over a second.
It has always been possible to see in the combat log or from close examination of the world who is getting hit with your Chain Heal. But because it is impractical to do so in the heat of combat, most of us simply ignore it and move on. Perhaps our eyes dart to the scrolling combat text to gauge the number of hits/crits.
This addon is designed to provide immediate feedback about who is being targeted by your class-defining smart heal directly in the unit frames. It has color and text channels, so you can direct its output anywhere except the center icon. I suggest the Border display area.
