This is something I'd *really* like as well. I need the ability to watch multiple targets and to ensure they're getting healing. If the information is already being collected, then adding a display seems like a natural next step. Just need to be able to have a window and set it to a Target (or targets) to watch.
We even have non-healers in the guild that wouuld like to be able to watch this.
Would love it if you could add it to the mod.
As an interesting aside - while I don't generally use my mouse to heal, I have been since installing this mod simply so that I could semi-watch two targets at once.
Would also love the ability to scale the displays, whether or not you add in watching multiple targets.
Thanks in advance.
