This plug-in for Grid adds a status for healing received in the raid. Source of healing is provided as text and the spell is provided as an icon.
See screenshots for example usage. My own use is to see instantly how many group targets my Circle of Healing has hit, so I can adjust targets for better coverage or switch spells.
Can be configured to show healing only from self or from any source in the raid.
Status is shown for a specified duration, from 0.5 second to painfully long.
