Thunderbird Toolbar Customization Problem

I would like to add Separators (lines) to the main window of Thunderbird (see pic). I installed the Message Header Toolbar Customize extension to add spacers and separators to any toolbar, but you can only add separators to the New Message (Write) window (see pic) and the Reply Window (see pic). As you can see, my main window does not have separators. When I click on Customize in the main window or the Mail Space, the separator button is not available for the Mail Space. Why am I not able to put separators on my main window/mail space toolbar?

An equivalent effect, that of providing visual separation, could be achieved by placing the flexible separator in multiple places. And, you could write to the addon developer to see if he/she might add that feature to the message header addon.
