I main a medic healer. I have some serious trouble keeping my head over who needs to be healed. The group frame is too far removed from where the actual healing happens, and is only useful for a glance overview.

I've found that if the shield bar is gone but health is full, bars will fade out completely. I've also seen them fade out in other situations, but I haven't found a definite pattern. Need to review the code that handles this to make more sense, and perhaps just offer a permanent "stay visible" option.

I've got a fix incoming for this. Seems to work well... just need to clean up a couple little things before it's good to go
