Very useful but probably breaks Forward Rated 4 out of 5 stars

Very useful, particularly if you are using a netbook with a small screen. Every pixel counts vertically, so the blank area above the first displayed header could be removed. It does indeed seem to break the Forward function by making TB quote the full headers in the message to be forwarded. The user can fix this by selecting Headers | Normal in the CompactHeaders addon's menu (if installed). This must be done once every time TB start if forwarding is required. The selection switches back to All every time TB starts. It could be CompactHeaders' fault of course.

This review is for a previous version of the add-on (0.8.2).
