Support for multiple *different* windows. Mostly
So, in practice, what we need to do here, is to create a NSUserActivity and, in there, store the payload (i.e. as userInfo) that the new window should receive in order to set up. However, currently, due to bugs in Catalina, these payloads seem to not always arrive. So in order to still support something, this feature currently loads a random entry if the payload is not there.
