Integrate Single toolbar layout with Bookmark, sidebar extensions

[SBZORRO]

Hello:

Considering the new FireFox sidebar, would Zen make sidebar extensions especially the Bookmarks integrate with Single toolbar layout?

I really like Single toolbar layout, but I also want as less clicks as possible to access the bookmarks.

Thanks for your works!

I found a solution.
Click "Extensions" on the top of toolbar, "Pin to Toolbar" the extension you want, "Customize Toolbar..." to drag the extension to the bottom.

But the bookmarks sidebar seems from a different app, and with it open, split view won't work.
