What is the enhancement in mind?

Provide a secondary threat bar, showing the threat against the "focus" or "pettarget" units

How should it look and feel?

These two additional bars would reflect *my* personnal threat against the mentionned units.

Please provide any additional information below.

As a warlock, i'm constantly DPS'ing two or more (cf Cho'gall HM) targets using macro modifiers to target different units.
And every once in a while, i'm pulling aggro from one of two off-tanked units while having much margin on the main target.
In this case, it would be awesome to be able to get a second and third optional threat bars to prevent this from happening.

Thanks for this great addon (i consider omen & such being great for tanks and raidleaders, but this one is better for dpsers)
