My Grid shows a counter on top left to see who has my SS and how much time it has left, a green dot close to that counter to show the FoL HoT that becomes yellow at 4s and red at 2, and another counter on top right to show who has my beacon and how much time it has left. I find it quite good considering Holy is like my third spec so i'm definitely not used to those cooldowns and have to check them frequently. Grid takes a bit to setup but it can show almost everything you want.
