Plays sounds when you gain Holy Concentration OR Holy Surge. Due to popular demand it also plays the "Critical Damage" sound and does full screen glow effects, which can be color customized. The UI only registers events being used so that it uses very little memory. If you only want 1 option out of the whole bunch its still worth it since it won't register the events you don't want.
/tg for command list, every option is able to be disabled or enabled for full customization
I started to localize the addon, but I need someone who has the german or french client to help, check the Localization.lua for more info if your interested.
If you have any question or suggestions I am here.
The sound files HolyConcentration, HolySurge and CriticalDamage were acquired from Tamarea(warlock lightning's blade, and the Sound Augmentation was performed by Bulwarkin (priest lightning's blade). I take no credit for them. However, I do thank them both for their hard work.
