Let's say my health is at 100%, and something hits me for 25% of my health. The existing BarFader plugin fades out the entire 25% chunk of my health bar in one piece. I don't want that. I do want the bar to smoothly slide from 100% to 75%.
I've seen Nurfed Unit Frames do this, and there's an old addon on WoWI from Gello that caused standard status bars to do this, but it doesn't work in 2.0, and obviously neither of these would help me get PitBull to do this anyway.
Sure it does, go into the frame config, then choose the BarFader option and check off "Smooth Fading."
