LF some for priest for WotLK holy priest for insta smite or flashheal to be on hud like in classic with spell activation overlay that is mage must since it adds procs on middle of screan and disappears when consumed... its cataclyzn built in addon for mage right ? :)

this addon simulate the "cataclysm proc" stuff you have mentioned https://felbite.com/addon/4843-cheese/
for sure it does that for "mage" class, I do not know if does it for "holy priest" procs as well.
You can check it out

For triggers I like MSBT although only some of the triggers come on by default and you have to configure the rest.

dude thank you for the addon. IT WORKS FOR HOLY PRIEST! but on mage it has upside down then it is on cata or wotlk classic spell activation overlay.. fireball goes on both sides even thou it has 1 cast but mages fingers of frost goes up as fireball should be and works properly but does not have the 2 proc visibilty nowhere rather then next to default buffs.. .so its kinda bummer for mage but gr8 for priest :) ty
