The lower zone itself cannot be moved but some of the contents can. Your mixconsole can’t be undocked from the zone because you can open it in its own window by going into “studio” and then clicking on “mixconsole”.
The editor in the lower zone can be undocked by clicking onto the arrow in the upper right corner of its window.
Generally, it seems that anything that can be opened outside the lower zone cannot be undocked “from” the lower zone.
The lower zone is just a convenience window for single monitor situations and isn’t fully page functional.
