Rather than having a cooldown bar go left-right, filling up as it goes from max to min, it would be neat to have a mode where the bar instead empties from right to left, to look like a true cooldown.
In particular, I'd like this because it would mean I could have an ability activated which fills the bar, then a cooldown is activated which has a variant of the bar that then empties itself again. It would give the effect of the bar filling, then emptying, which would look really neat compared to 2 instances of the bar filling.

Apologies if this is already a feature, I didn't find anything like it in the documentation. I know a resource bar could technically do it, but it would be way more cumbersome and not as smoothly animated as a proper cooldown bar.

This is actually already a thing (should also be supported by cooldown bars, since resource and cooldown bars are practically the same); you can specify an inverted field with a value of true (it has a value of false by default)

Woo, that works exactly how I wanted it to! Thank you!
