Threat bar location Elvui only options are left and right chat. Seeing how you have 8 data panels one could be for threat. Or have a module that is only for threat.
On the S&L DataText module under RightChat another section could be for labeled threat with the with hight, width, color transitions, and spec (this one would have to check spec to enable thus changing the coloring threshold. This would all be on one side of the bar the other side would be the tank or have the threat overlap the tank threat think heal prediction. This could still work with the tank spec. This would just change the threshold for the colors but keep the tank bar behind the dps bar. Names could be added on another version once edits are made to the working function.
Don't know if this is something you would like to add in or if it should be passed on to be implemented as a base for Elv or for CustomTeaks. This is me being more so picky about only having what I need on the screen. The threat is a non-issue at most times but something very simple like this could overtake Omen for some people that don't need to see more than one. I know you can condense Omen down but why not add it to a bar that can be placed cleaner.
