Especially when I receive big messages containing more advanced HTML than usual (lots of images and formatted text in various sizes), the ability to collapse the header frees much needed space. This is such a small, simple and highly useful addon that I have to write a review and contribute to the well deserved high star score it has. The first thing I thought upon installing it was: "Wow... Why isn't this part of TB3's native features?".
