Ive wanted to tweak the way Tab Target or TargetNearestEnemy works for a long time. Basically, I want to make my TargetNearestEnemy very focussed. See Diagram:

B
.
.
.
.
A .

ME

Currently, TargetNearestTarget will normally pick A before B because A is so much closer than B. I want it to pick B and only B. If I want A, I want to be able to look right at him and hit tab to retarget (i.e. a bit more like FPS targeting). I'll settle for picking up B before A, but I would prefer to only have B. I dont even mind clearing my target before reacquiring. So... I want TargetNearestTarget to put more priority on the targets that are in the center of my screen before the closest targets.

So far :
- I can increase the range of TargetNearestEnemy to a large range (through the addon oTweaks or by changing the config.wtf file)
- I cannot reduce the Width or Radius of the TargetNearestEnemy Function. The addon oTweaks has a "tabRadius" parameter... but it doesnt seem to do anything.

Anyone have any ideas on how to get this kind of functionality?
