Tracks the HP of units with a raidmark and displays how many players target that unit.
The HP can only be updated if someone in the raid has the marked unit as a target/is the marked unit or if it is visible as one of your nameplates. If the unit dies or hasn't been seen for a set amount of time the hp bar disappears.
If you change the size of the bars/font, make sure to change the max namelength in the custom options.
