Hello everyone!
I am trying to find a version of FB Heal Box that works on Vanilla here. I did find one version, but it appeared to be a BC-era update, so I'm back to looking around. The current (WoD) version of this addon is called Healium. In the meantime I'm using Grid and Clique with no problems, I just prefer the Heal Box/Healium interface. Thanks for any information you can provide!
