Allows solo setting your own personal Main Assist, but also allows group leaders to sync the Main Assist with the whole group (if enabled).  

Has a UI, sticky targeting aka auto assisting, slash commands, allows Main and Secondary Assists, has group notification when the Main and Secondary Assist changes targets.  
Notification however depends on the MA/SA having this mod installed as well.

Notes about the UI:

- A small skull is attached to the minimap for toggling the UI.
- Where the MA and SA's name displays is also a button.  Left-clicking on the button will assist the person listed.  Right-clicking will bring up a context menu of people you can change the MA or SA to (group members and current target only will show up)
- The plus button's allow you to type in the name of the person you want to set to MA or SA.
- The group check box enables all group functionality.
- The sticky check box enables auto updating your target to the Main Assist's.
- UI window is lockable.
