Loot control
Sneaking while activating a killed NPC will (usually*) auto dispose of the corpse after looting, useful to get rid of the corpse without cluttering your inventory.
 
*Known limits: if you slay more than 10 enemies in a cell, you will have to wait for next cell change for freeing some script slots.
Scripts are started from hit voices, so it may (rarely) happen they don't start.
 
 
 

Note: this mod is probably made obsolete by the excellent "Don't loot on dispose" option provided in last Morrowind Code Patch
