I've made a UI (for stock) to show blinking warning when groups mates health goes below 60 percent. It will also warn the players health as well in the player window.. Greatly beneficial for raids and group situation where at times we tend to forget to monitor our groupmate's health.
It has other features too.. You can download it here.
