In need of an Ice Barrier addon

[ExtraEye]

I'm surprised no one has made an addon for the Ice barrier yet (maybe I missed it?) as it could be very useful and seems like a relatively uncomplicated thing to make an addon for. I'm talking about something like a bar (but doesn't have to be) that shows how much more damage the ice barrier will swallow.
I would be very grateful if someone could make an addon for this.
