SetShowQuestItems
From GECK
A function included in the GECK for Fallout 3.
Description
This is used to show or hide quest items in the player's inventory (normally the player cannot drop or sell quest items). When flag = 1, quest items will be displayed in the player's inventory (default functionality). When flag = 0, quest items will be hidden.
Obviously this function has to be used in very controlled circumstances to prevent the player from permanently "losing" all his quest items.
Syntax
SetShowQuestItems showQuestItemsFlag:int{0/1}
