The "Mark" header will allow you to disable/enable and push
to the top of the list the marked files group (if any)
with the same criteria as the last sort you have made.
Click on it and wait at least 1 second and the Mark menu will be displayed.
The info at the right of the menu is the criteria to join the selected group.
If you hold down the shift key when the menu is open you can disable/enable the selected group.
If you hold down the option key when the menu is open you can disable/enable all groups.
You can also disable/enabled the Manually marked group.
If there are active groups you can choose move to... "...only active marked files" from the "Move to..." button. If you choose move to... "...all marked files" you can move all marked files also if they are not active.
