Fixed that problem where the position didn't seem to save correctly. It occurred if you were running a viewport mod that offset the bottom edge of the playable area.
Version 3.1.2
Added the option to display Absolute Threat defecit (ie. the value of how much threat is needed to pull aggro). Optimised some calculations for better performance.
Version 3.10.a
Re-written from scratch to use Blizzard in-game threat values.
