I can't believe there are no native controls in Thunderbird for this. For anybody working on a non-massive screen (like, say, a mid-range notebook might have) the default header area feels uselessly bloated. This add-on fixes that right up. So simple, but it makes the experience so much better!

I would agree with a previous reviewer - it would be even better if I could choose to remove the header pane entirely. But it's still profoundly useful as-is.
