Id like to see some new hooks added to the items so we can use them in the cloned objects like:

onItemLeftMouseButton():
A hook which is called when the item is pressed on with the left mouse button, the default behavior is: By specifying this hook for an item you can make the player unable to pick up the item, or play some special
effects etc. when picking it up.

onItemAdded():
A hook which is called when the item is added to an inventory/slot/container(sack, altar, etc..)

The following party hook that already exists might be something that might interest you:
onPickUpItem: a hook which is called when an item is picked up. The function gets two parameters, the party itself and the item. If the function returns false, the pick up action is cancelled.

Indeed, that might replace the first proposed hook, ill try it out.

onItemAdded does sound very useful actually =)

Well both would be as the current "onPickUpItem" hook is not called when picking up from the inventory making it quite useless.

Request:
A monster "onAggro" hook would also be nice (maybe name it a bit differently though ).
That would be called when a monster spots the party and turns to attack it.

ah I like that one, so when you're spotted an alarm goes off, or there is "insta-kill" if you are supposed to sneak through the map, or the lights go out, etc

Another request:
onCraft
A hook in the recipes when crafting an item. Should returns crafted item, champion that crafts it and which item is used to craft (e.g. mortar & pestle, hammer & anvil etc). If false is returned, no item is crafted and the materials are not consumed. If true is returned, the materials are consumed, no matter if they actually crafted something.
