When all visible subs are removed from an item (e.g. by moving them) it's impossible to view the remaining hidden** subs by using the "show all subitems"  item context menu option -- unless one  does a refresh.

 

Before a refresh, the parent will be displayed as if it had no subitems at all. (This bug appeared a few versions ago)

 

Of course this can be a bit dangerous : if one deletes the parent thinking it has no subs, it's easy to delete the children too (IQ warns the  user that it will delete subitems, but...  )

 

 

**(e.g. hidden because of the filter settings)
