Add New "Message Header Content Menu"...

[AVWDiamonds]

Hi Developers,

I have idea to add my suggest, after I saw large Message Pane Header with many lines, tried to uncheck or hide lines down, but limited I saw. Now, here is Image I uploaded; with number I drew on it:

1, 2, 4 and 6 are not needed to show in Header space, because all are already list on above on Message List with purple highline block. I do not like large Message Header, need it turn to Compact Header in ONE Line of Message Header (like one in Top line is perfect with menu icon with letter), it is all I need. 

Can you add 1, 2, 4 and 6 with Hidden items (lists) to "More\Customize\Message Header Setting" Content Menu on left side of Message Header?

Many of us will like it very much as far as we need to make Message pane large and more readable space!

I looked over Thunderbird App, and I found it best software ever I tried than Outlook App/Spark Desktop App!

Thanks!

Andrew

MattAuSupport,

Thanks for right extension: Compact Header, it works flawless with content menu, only on top and bottom list. I really like this extension, it's quick and easy to click on and off.

I tried other extension: Message Header Toolbar Customize, I looked and tested it, until I accidently clicked Hide Toolbar, top line with icons disappeared, I had hard time trying to find it unhide. but impossible. so had to remove it. Compact Header have "Hidden.." on content menu easier to hide and unhide, except second extension. 

Again, thank you for helping me with right first extension!

P.S. Let you know that I will write with image how 3 out of 4 extensions got crashed Thunderbird in new post.
