Hie,
I wonder if with the 'OpacHiddenItems' system preference, you can
reproduce what's managed by 'hidelostitems' system preference.
For example, if LOST values are 0,1,2,3 (0 meaning not lost), you
can use in OpacHiddenItems :
itemslost [1, 2, 3].
So can we imagine removing 'hidelostitems' ?
Best regards.
