Good start!
Just need an option to hide whole pane to make maximum use of the screen space (not when working with message in separate tab).
Because msg information is in the list and buttons can be added into main toolbar.

This is now (almost) perfect. I do still have a feature request, if you are able/willing to do it, though. When showing the compact header for an RSS feed article, the older add-on associated the article's URL as a hyperlink on the Subject so that I could just click on the Subject header to link to the full article. Here, I have to expand the headers in order to see the web address to click on. That would be a nice feature if you can do it. Many thanks.

Works perfectly and a nice replacement to the Compactheader extension.

Very useful! Could you just please update the subject line, so that it displays a partial subject when it's more than one line?

Yes, next version, send me your email and I'll send you a beta.

EXCELLENT! I like the option for a one- or two-line compact header. Thank you!

Good replacement for "compact header", thank you very much!

One (hopefully small) feature request: instead of showing From and Subject in compact mode, allow showing Correspondents and Subject -- this way, you automatically see senders (for message you receive) or recipients (for messages you send), which is more useful information than seeing yourself as sender when viewing message you have sent.

I would like the following feature.
When the focus is on the message content header's color should be darker or when on the list be lighter.

I would have given more stars but I am concerned about the permissions required for installation which says the extension "requires your permission to have full,unrestricted access to Thunderbird and your computer". Why the computer ?

This is the standard permissions popup for all add-ons.

Подтверждаю предыдущий комментарий — после перезапуска строка открывается в развёрнутом виде и приходится дважды кликать, чтобы её свернуть. Более того, это надо проделывать и с другими письмами.

If you restart Thunderbird, the compact display will be canceled.
I want the option to always be compact.

Delete the first review. Didn't see the button to swap sizes. :(
My only wish is that there was a little more space below the second line of the shortened header. If it had that, there would be 5 stars.

Ok, the toolbar button is replaced by a twisty in the header area in the next version. I'm just waiting for it to be approved. If you send me an email I can send you a preview.
