Option to keep tabs toolbar without tabs when vertical tabs enabled

[N2ezr]

Recently, Nightly changed the behavior. Now, when you enable vertical tabs, the tabs toolbar disappears and all buttons from it move to the navbar.

This is definitely cool, but I would really like to be able to leave the tabs toolbar without tabs. Just as an additional toolbar. Even if it's a secret setting via about:config, still. This would be an incredibly useful feature for css theme creators, so please hear it

I actually used the tabs toolbar to put all my bookmarks in (and used a Vertical toolbar add-on for the tabs) and used the bookmarks toolbar itself for other buttons.
(nav-bar only has buttons/elements regarding navigation)

Therefor the latest update regarding vertical tabs kinda messed up all my toolbars.

So yeah. Keeping the tabs toolbar when vertical tabs are enabled in one way or another would be appreciated.
