I am been trying to find the answer to my question via google, but somehow I cant find it.
So I am turning here in the hope that someone can answer this.
I am currently using healbot addon, but now I would like to change the way the HP bars flow. Currently they move from right to left, as the char takes damage. I would, however, like them to move up and down instead of right and left.
I'm sure you're no longer looking for this answer, as it's been over a decade, but you can change the direction that the health bars flow in HealBot menu under: Skins >General>Frames>General>Bar Orientation
