As per what the title says, I would like the option to be able to create aura bars for specific abilities/effects that are tied to our classes/specs, or even equipped items, like trinkets and other. Currently, there are addons out there that can do this. I’m using NeedToKnow for this very purpose. Again, though, being able to create simple aura bars to track for example a buff/debuff on myself, or as a hunter – on my pet, that would indeed be a good option to have as part of the default UI.
You could implement the function to where you right click an ability/passive effect in your spellbook, or perhaps, you could have a separate interface that shows all these abilities/effects. From there, you can choose which unit to monitor, what type of effect you want to track, and then other misc options, such as how you want it to be shown as a bar. And with that, also having the default option to move said aura bars around on your screen to a place where you want them.
Why do I want this? There are certain effects that I prefer to track visually via an aura bar, rather than an icon.
