Addon idea/reguest: low morale/power warning

[kwiat_w]

When I play as a healer and fight gets really intensive I'm monitoring closely morale bars of my party members, but sometimes I forget to look at my own
so I'd like to request an addon that displays visual warning when your power or morale goes below certain level.

It would look like this:
WARNING!!! It's a wow screenshot!

It would have red color for morale and blue for power. A big text message in the center of the screen wouldn't hurt either.

From what I have seen in addons that already exists it should be possible with current api(?).

EDIT:
I just noticed I've posted this in a wrong forum section. I apologize and promise not to make this mistake again. I ask admins to move this to " Interface Requests" forum.
