Blizz Unit Frame Modifications?

[Roane]

(I'm full of questions today. It's a slow day at work.)

Is there a mod that will: 1) Make the health bars on the standard Blizzard unit frames change color as it decreases, and 2) Make the entire frame clickable, not just the portrait? (Might only affect party pet. Not 100% sure on party and focus frames.)

For reasons I could go into, but will try to spare you from, I want to keep the standard Blizzard unit frames, but especially the second one of those problems I'm trying to address can be really annoying as a healer using Clique. I looked at oUF Neav, but it looks like it doesn't contain some of the functionality of the basic Blizzard unit frames (druid mana bar, for example).
