What functions do you miss most from hpl2?

[PythonBlue]

Might not be easy to re-implement, but I personally miss the inventory from Amnesia and Penumbra. Thankfully, I just read in the wiki that it is possible to specify new entity types if need be, so it might be possible, even if difficult, for us modders to re-implement.

EDIT: I realize now that was a bit irrelevant, especially since the inventory is no one function, so please disregard this reply.
