RaidCluster

RaidCluster is an addon designed to display clusters of players as counters that increment when players are close to each other. It helps healers identify the optimal targets by indicating where healing efforts can be most effective. It supports Holy Light Glyph, Chain Heal, Wild Growth, Circle of Healing, and Prayer of Healing spells.

Additionally, it can trigger a glow effect on a players raid frame when one of these spells hits the player. All settings can be accessed under Interface -> Addons -> RaidCluster and include various appearance and loading options.

Furthermore, it supports dual specialization.
