Toolbars were discouraged since 2009 and I would only discourage them further. A better way to pin folders to taskbar is needed.
Options are not is generally useful. Sane defaults would be better. Cloned taskbar is what Windows 8 went with and going macOS way would present challenges. I see the usability benefits of ignoring full-screened monitor; however, I don't generally use multi-monitor as most users.
