So at the moment when you slip a note under a door the displayed text to those on the other side is:
[Character] dragged an item out toward [building].
I’m not so sure that the character’s name should be visible here because you don’t know who is on the other end of a knock, so why should you mechanically know for certain who is sliding a note under a door? I’d suggest it should read more like this for the people on the other side:
An item was dragged out toward [building].
I think this would create a sense of mystery of ‘who is on the other end’ which may lead to some cool stories which, at the moment, can’t really happen because everyone always knows who has sent through what note.
