ok I understand, so I sume up:
- when the mouse is not in the specific area, you need an FTL-style-button for your heals
- when the mouse is in the specific region, you heal by mouse over, so you don't need FTL-style

Some questions I have are:
- the key you use for healing, are the 'empty' for your dps-toons and your tank(s), so only the healers do something when they are pressed?
- Do you need the mouse-over-healing from every-window or would one window (like the window of the tank) be enough?
