In reply to Adrianl:
"Shift-double click with the Select button on the icon of an open directory in the Filer, and it closes that directory and all subdirs etc."
Now that one really is useful to me (and anybody else who uses !MoreDesk)
I run !MoreDesk with 7 screens, using each screen for a different set of tasks. Very often I need to access a directory opened on one screen from a differernt one. The problem is in finding it!
Until now I have had to either search through all the screens, or navigate menus - Fetch > filer...
Now it is possible to close the "mislaid" directory wherever it is and open it again on the current screen.
