Hi. This addon was NOT made by me. As far as I can tell, the original is here:

The lucky charms nameplates have had target level and name over top of the health bar, making it hard to read/look at, so here's my attempt at fixing it - I only changed about 5 lines-ish.
Updated it - see notes for details.
