VisualHeal is a small and simple but powerful tool for all classes that visually shows your heals to others and heals incoming to you from others by means of two types of information-packed, yet intuitive bars:
The Outgoing Bars: Whenever you cast a healing spell a bar will appear for each target you're healing, which shows the health of the target(s), the incoming heal from others as well as the healing you are about to cast. This makes it easy and fast to determine whether or not the heal is appropriate for the target(s), as well as giving a useful overview of the effects of the healing being done.
The Incoming Bar: Whenever anyone is healing you a bar will appear, showing you your own health and how much healing will be done. If several people are healing you, the heals will be added up and the total incoming heal will be shown. This makes is easy to determine whether or not anyone is healing you, or you should drink a potion or use bandages (or heal yourself if you are a healer).
VisualHeal significantly helps cooperation in large groups by showing exactly what is going on in a compact and easy to read format that makes it possible to react to the information before it is too late. It is also useful when not in a group, because it visually shows the size of the healing your are casting in relation to the health of your healing target, and instantly makes it clear how much healing will be done.
Configuration: Use the Blizzard standard interface menu item from the main menu or type '/vh' or '/visualheal'.
Addon Communication: VisualHeal does not use addon communication. The information about healing is retrieved purely from the new Blizzard API's added in Cataclysm. These are known to have problems with some spells, and in some cases not all heals to all targets will be shown, and the heal sizes may be inaccurate in some cases. These deficiencies must be fixed by Blizzard. If you suspect that something is wrong with VisualHeal try to compare with your unit frames. If these exhibit the same defect, it is not a defect in VisualHeal.
