Works for all WoW client versions!
This addon simply automatically accepts resurrections. However, by default, it will not accept resses while the resurrector is in combat. This is useful if you for example have a druid that combat resses you while the group is wiping, and you want to save the res for when the pack has reset. You can change this setting by using a command.
Commands (type them in chat):
/aar - To list all commands
/aar 0 - Disables the addon.
/aar 1 - Enables the addon.
/aar combat 0 - To not automatically accept resses while the resurrector is in combat. This is the default.
/aar combat 1 - To automatically accept resses even if the resurrector is in combat. Setting this to 1 will also make you automatically accept resses from people outside of your party/raid.
