Hi, this is a nice extension, but unfortunately it doesn't work anymore in current aurora version Thunderbird 23.0a2. When trying to send a message, you get an error message saying no recipients are specified. With this add-on disabled sending of messages works again...

This review is for a previous version of the add-on (1.5).

Thanks! I find this extension very useful, because it allows you to see more new messages in the thread pane when reading your mail.
