Noob question regard Hate meters

[webin]

I had my first groups last night with the GU51 changes and updated ProfitUI, and the hate meters are confusing me a little. I'm assuming the circle-and-swords hate percentage window is SOE's (based on the fact that it wastes a lot of space for one number), but is there a slimmed-down Profit version? Is this the only way I can see when I'm about to pull aggro off the tank?

In the group window, there are orange or red lines for each person, similar to the power and health... I assume this is an indication of hate, but it didn't seem to show meaningful information. Between fights, it's be completely full for three group members, and empty for the others. I didn't really get enough observations during fights (because I was busy watching the new autoattack bar and dealing damage).

I feel a bit like a noob because I think I need a tutorial for the new hate information in the UI.
