I wouldn't mind a minor change to the enmity list as well. A big thing I'd like to see is for things to flash when you're about to lose aggro, a lot of newer tanks have a hard time dealing with a lot of targets and it would cut down the need to cycle through to check your enmity against the party's.

My second thing with the enmity list, relates to tabtargeting a bit. The way the list works now is you need to aggro the mob in some way for it to be on your list. Line of sight/initial aggro, hitting it, healing someone who has aggro on it, your pet hitting it/healing someone with aggro. I think they should show up on your list as soon as someone in your party aggros it, regardless of if it actually puts you in combat or not. This would make them easier to select (through the list), allow tanks to see if there is anything someone else accidentally pulled, and allows healers to know when trouble is coming and can react on it.
