KLHThreatMeter
KLHThreatMeter is like a damage meter, except it records your threat. By monitoring all the abilities you use and checking your talents, armour set bonuses and buffs, the addon can recreate the threat list of a mob. This makes tank transitions simple, and allows DPS to maximise their damage without pulling aggro.

Note: due to the intricacies of threat, it is only possible to accurately determine your own threat, because you don't know what talents other players are using; also some abilities can only be detected by the player who uses them. Therefore everyone in your party or raid group needs the addon installed to have their threat appear on the table. In practice only the tanks and DPS need to have the addon, healers might use it to check upcoming tank transitions or warn DPS who are going too high.
