I have a horizantal grid layout with names and health deficit on the text items. I also use the side indicator thingy.
Border : Aggo Alert > Healer Priority
Center Text : abbreviated name
Center Text 2 : Health deficit, death, offline
Top left : PW:S, Weakend Soul
Top Right : Magic debuff, Disease Debuff
Bottom Left : My Renew
Bottom Right : INcoming Heal, Low Mana
Frame Alpha : death, offline, range
Left Side : Prayer of Mending
Right Side : Fear ward, Inspiration
Top Edge : Missing Divine Spirit (OOC only)
Bottom Edge : Missing PW:F (OOC), Clearcasting (so i don't miss my own and can get annoyed about how often the mage one procs)
So in the following Dyv has PoM, my renew and fear ward.
An OOC version showing missing buffs:
