Add the second highest threat to the AOE bars when you have the top spot.
Visually similar to what the pull-out bar looked like on Omen 1.
This would be extremely helpful to tanks when having to build aggro on multiple targets, as it would let you see if you need to go back to your primary target, or could switch to a third or fourth target first.
And one more:
Allow the offset of the Title and Modules frames to be configurable.
Ok, I went back and updated to the latest version. And the problem reappeared.
Went into options Quartz/Player and the "Disable Blizzard..." is checked.
Disabled it and re-enabled it, now the Blizzard castbar is gone.
I've attached my Quartz.lua saved variables file.
Hope it helps.
