Original addon at https://www.curseforge.com/wow/addons/atonement-assist
Addon stopped working after BFA prepatch and wasn't updated since 2016 so this is a continuation to the project and restores it to a functional state.
This addon makes it much easier to track your atonement or renew depending on spec on party members when using Blizzard raid frames. Green border when > 5 seconds left on atonement/renew, orange border when < 5 seconds left on atonement/renew, no border when no atonement/renew present.
