Please read '+help +inv' again.
+inv/link <Mod Item>=<Main Item> .. This will add Mod Item as a
modification of Main Item. If Main
Item is blank, it will unlink the
Mod Item. This can be used on your
inventory, cyberware, or bioware.
+inv/remove <Item ID> ............. This will remove an item from your
inventory, including installed
cyberware or bioware.
You can use these commands to link modifications after chargen and remove gear, including cyber/bioware. I think this removes the need to +kill to make sheet changes.
Ps. I changed the cyberware and bioware layouts on the +sheet. Enjoy.
