Despite the name, this mod has little to do with healing directly, and can be useful to lots of different players. Presently it does two things: 1) It effectively makes the Auto Self Cast option character-specific. Blizzard's normal UI behavior sets it on an account-wide basis. 2) It allows you to set an option whereby the auto-selfcast behavior changes whenever you are in a group. The usual use of this feature is to solo with auto-selfcast on but deactivate it for groups. The option is displayed in the basic interface options under the checkbox for Auto-self cast.

Planned updates: Thinking I'll probably roll a menu for setting your self-cast modifier key into this mod, since a lot of people seem to want that functionality back.
